Rifles and Ranges

There are two battlefield technologies that really set the Franco Prussian war apart; the first is that both sides used breach-loading rifles, the second is that the artillery of both sides were equipped with percussion fused explosive shells (although one must remember in the French case that it was only under the republic that the shells worked, those in stock at the start of the war having been the victims of corrupt procurement and shoddy manufacture -- only the timing mechanism worked, although they were designed to have a percussion backup).

Getting the battlefield effects and relationships of these weapons and each side's tactics is critical for representing the period.

However, a couple of principles:

• Close combat includes (indeed primarily is) close range fire combat. Those instances, for example, where infantry stopped cavalry cold with rapid fire at 100m will be represented as a part of the charge/defend cycle. Why? Because measurements under a centimeter are fiddly.
• Range and fire effect breaks should be the same for both sides. That does not mean that performance should be the same for all weapons for any range, but that if, for example, the needle-rifle gets a particular fire effect in the 0-300m range, the Chassepot should not have it's best range band from 0-400m. Why? Because this creates narrow sweet-spots which are both fiddly to measure and not, as far as I can tell, actually exploited historically.

So, some basic range data.

Weigle (1870) notes that the Chasspot was sighted to 1200m, but with an effective range of at most 500m. This is in general agreement with other sources. There are example of longer range fire being effective. One should note that the Prussian Guard was stopped 700-800m from the french line at St. Privat.

The Dreyse, in Comparison, was sighted to about 600m but considered effective under 300 - and German practice was to not fire above that range.

There were a number of other rifles used in the conflict - the Podewils, system tabatiere, various rifles obtained by the Republic from overseas sources - but the most important can be modeled as one of the two main weapons.

This suggests a set of range bands like this:

	Close		Effective	Long	Extreme
Dreyse	Melee		300	600
Chassepot	Melee-300		600	900	1200

Now, the problem with this is that it only allows for technology. Under 300m, most sources agree that German fire discipline and marksmanship training was superior.

The von Tschischwitz Kriegsspiel makes another interesting point. Men did not stand by under fire. According to the Kriegsspiel, men in a firefight under 300m would only hang around for less than 2 minutes (one Kriegsspiel turn). His table goes out to 20 minutes at 700-800m.

This does suggest, with 1-2 hour turns, that fire combat is part of a process of combat that starts with troops entering the beaten zone with some definite objective in mind, and that the success or failure of that objective should be resolved before the turn ends. In this conflict, we actually have an interesting asymmetry. The French actually have the option to advance on the Germans with the intent of entering fore combat without the Germans being able to fire back.

I must think more on that. In the next post, however, I will look at artillery performance.

Inches or Centimeters?

In the anti-finicky department, I am thinking of doing measurements in inches of 250m rather than in centimeters of 100m.

• The upside of inches is that we are using rulers with bolder and more clearly marked units.
  
• The downside is that, if I keep everything in even inches, then the breakpoints for some ranges may not be exactly what you find in the standard texts - Dreyse ranges may break at 250/500 instead of 300/600 for example. However, I think 5mm of fuzziness is not a high cost to pay for faster distance readings.

A quick survey on TMP suggests that, while some folks have to go to a bit of work to get Imperial measuring tapes and rulers, they are obtainable by some means pretty much everywhere.

An initial vision of sequence of play

Lets see how much this changes as we go along:

Embedded within the usual administrative phases we have (assuming a turn equals about 2 hours):

• Shared operation movement phase where formations and blinds more than some distance from the enemy and in a formation and state to do so move rapidly, but end at a distance either still out of range or at some long range. This should probably include or be proceeded by some recon component, where blinds are revealed voluntarily or otherwise. Movement would be a good long way, say up to an hour's distance. I think some sort of alternating movement by brigade.
• A deployment and intentions stating phase.
• A series of combat phases, alternating with the sequence driven by initiative. This could include a number of cycles until both players decide to stop attacking or are unable to. Movement in this phase would be limited to a scale kilometer or so.
• Perhaps a closing operational phase where players exploit or consolidate their situations?

Glancing at movement, Kriegsspiel offers 100 paces a minute for foot, without a whole lot of variation -- about 4.5 km.

Volley and Bayonet offers 1.6 km for a 1 hour turn operating as a mass, but in march column 3.2km cross country and 4.8km on roads.

Ardent du Picq at one point mentions that column of companies is a poor way to move troops over any distance because it is close and confining, and they will tend to suffer from heat exhaustion.

Morale and other unknowns

Here's a good point well made:

http://prometheusinaspic.blogspot.com/2010/11/grand-tactical-game-morale-or-not.html

I agree with the idea that the effects of combat on units in a game should mostly be morale effects; and that separating morale and casualties into separate tests is avoidable and probably best avoided.

That does not mean that there are not cases - many cases - in the war in which the primary effect really was physical. The 52nd Brandeburg regiment, for example, during the battle of Mars-La-Tour, lost a third of its strength mostly in the attack on Flavigny. In the same battle Cuirassier of the Imperial Guard lost more than a third of its numbers in a single charge.

Still, while dead men cannot advance morale is still an important effect. It was the remnants of the 52nd that the Cuirassier charged; they stood their ground and decimated their attackers.

Still, the morale of a unit is not always clear to its officers -- or to the men in the unit themselves. Patry, in The Reality of War, describes an incident during the defense of St Privat. His battalion was pinned down, tanking casualties but shooting back and apparently in reasonable shape. The commander stood, gestured, encouraged his men -- it was time to move into a more forward position. Party describes himself a standing up, certain he was about to advance -- then he and everyone else in the battalion heading for the hills.

On the other hand the Prussian Guard, which lost a quarter of its strength in about 20 minutes in front of St. Privat, and was pinned down for an hour, was able to stand and advance as the Saxons turned Canrobert's right and the French defense started to break down.

Here's roughly the mechanism I want to use. A moving, active unit accumulates hits which are resolved immediately and have their effects which may include degradation in capability or an unwillingness to move. If enough hits are take, the unit breaks and will probably just be removed from the table. Some hits should probably be reversible with a deliberate effort to rally the troops. Some proportion will not.

Once a unit goes to ground - either voluntarily or pinned as a combat result - fire will not cause immediate hits, but potential hits. Those hits will be accumulated until a unit faces a "test" - a "moment of truth" (I like the second phrase better, since it does not have the baggage of "morale test") and then they will be resolved and the actual hits applied and resolved. Potential hits may still cause effects such as a slacking off of fire (are they dead, or conserving their ammunition?).

I have two moments of truth in mind at the moment.

• The player attempts to move the unit, either forward or back.
• The unit comes under close assault

The sense I get from the accounts I have read so far is that once infantry have settled in, you have to use the bayonet to get them out.

Lets Talk About Frontage

Not of the stand, but of the zone of responsibility expected of a higher-level formation.

I'm just going to grab a few examples, and look at the number of units dedicated to the frontage covered.

At Gravelotte-St Privat, according to Waro, French III Corps covered a frontage of about 4km. Based on the OBs posetd earlier, that is roughly 16 regiments of infantry, 16 batteries of various calibers, and 6 regiments of cavalry. That is, crudely. 8 men a meter.

At the other extreme, at Wissembourg (excluding the detachment in the town, and using the OB from 1870 and the map from Waro) we have 5000 men defending a front of about 2km. Crudely again, 2.5 men per meter.

Of course, this war is far from the linear warfare of the 18th century. On the breach-loading battlefield, at the scale of armies, the number of men that can stand shoulder to shoulder two ranks deep in a certain width really does not help us understand the frontage our stand should have. It is my belief that we have to:

• look at the formations that existed withing the tactical doctrine of the opposing armies.
• determine (guess?) the trade-offs between control, firepower, morale and close combat capability implied by that formation
• establish a pattern of the placement of the stands of a formation (still in my mind a division) so that the tactical formation is uniquely indicated, and the pattern is both evocative of how the formation would appear on the ground and visually attractive when looking at the table.

So how do we want the figures to look on the table? Well, we want them to look like this, of course:

Alternative stand counts

Without looking at detailed organization, lets work back from those raw stand numbers and consider some alternatives.

			French				German
Men/Stand			Infantry	Guns	Mg	Horse	Infantry	Guns	Horse
Foot	Guns	Horse	118000	360	72	12500	152000	636	20000
2000	12	500	59	30	6	25	76	53	40
3000	18	750	39	20	4	16	50	35	26
4000	24	1000	29	15	3	12	38	26	20
5000	30	1250	23	12	2	10	30	21	16

The first three columns offer ratios of represented troops by stand type. The first line of very large numbers are troop counts - those are reverse engineered from the stand counts in the earlier OBs so don't take them too exactly.

The fist line below shows the assumptions of the earlier posts. The next three offer alternative ratios and the number of stands derived from that ratio. This ignores the need for a compelling and reasonable organization of the units, but it does help us think about how to structure the information.

A quick tentative OB for Gravelotte/St Privat - French

One immediate observation is that, at 3cm frontage, that is 3 running feet of guns. Guns were important, sure, but that is unmanageable and visually overwhelming. I am going to either have to find a way to get the guns on 20 or better 15m frontage bases, or I am going to have to re-structure the OB to drastically reduce the number of gun models.

I Go, You Go, We Go, Hugo?

My first miniatures gaming experience was Charge!; early on I got used to writing orders and moving my figures at the same time as my opponent. Always seemed to work well, and we never that I recall had a problem that could not be solved by breaking the moves into quarters.

More recently published rules work that way as well. Both Command Decision and 1870 use a chit to express commitment to an order with the details worked out in a shared movement phase.

Other rules use a system where only one player, and generally one formation, is moving at a time. This may be a completely alternating system where I move all my units and you move yours, or it may be an interleaved system where sides alternate moving subunits either picked by the player or by a card draw.

My main experience to compare these two approaches in rules for the same period and level of play has been Command Decision and Blitzkrieg Commander. Both are excellent systems, well supported, with an enthusiastic following.

Both games were full of surprises, but they came from completely different mechanisms.

In playing Command Decision I found that most of my decision making took place in the few minutes I spent laying chits. During the shared movement phase I discovered the implications of the intersection of my decisions with my opponent's. My heart would sink, my hope would be buoyed up, but I would not be making decisions.

Playing Blitzkrieg Commander, I find myself constantly making decisions. Do I try to get another action, do I shoot or do I move if I am the player who's turn it is? Do I use my opportunity fire now, or wait f I am the non-moving player?

I like making decisions. There is a momentum to how battles are fought, especially in the days before radio, that should constrict how quickly a formation can reverse a decision made and disseminated an hour ago. But within the bounds of that overriding decision, there should be decisions for the player to make constantly through the game.

Lets make that an objective:

• Every player should have decisions to make constantly through every turn.

Another audience to consider (especially since I am liable to be one while developing the rules) is the solo player. Inherently, in solo play, only one formation is moving at a time. I am not sure that having to wear both hats at once to work out shared movement situation will be all that much fun.

So, looks like I will be going with some variation on I Go/You Go. But I am not sure of the details yet.

Just a quick aside on sequence of play. While I like fluidity in rules, I do (probably because I played boardgames for so many years) like to see pretty much every key activity allocated a place in the sequence of play. The SoP is not just an order in which things are done. It is a checklist to make sure that we do not forget anything.

Lets talk about time for a second

First, lets review one of our guiding principals. I pulled 6 hours out of the air for a duration, but after a perfectly unscientific but interesting poll on wd3 and some other discussions I have decided to halve that, and set 3 hours for a target. That is not long for a big battle; I am also allowing some slack since 4 hours seems widely acceptable. But it is easier to use up setup, take down and chat time.

The members of a group I had a chance to play Triumph of Will with mentioned that they never got to use some of the interesting features of those rules for rallying troops and bringing them back into action because they only had a pub evening to play the game. I want to avoid that problem.

So, a 12 hour battle in 3 hours of play -- we will have to trip along with an average of 4 times time acceleration. Of course, not every turn will take the same amount of time to resolve, but that average will be have to be kept in focus. Time and motion study time, I guess.

Lets talk about blinds and dummy units.

One way to provide real uncertainty is to use dummy markers or blinds to represent the real or suspected presence of forces not yet confirmed by the enemy.

I have played one game of this type -- I Ain't Been Shot Mum from Too Fat Lardies -- but only once. I do plan to test some of these ideas with Hearts of Tin the next time I have a chance to get out my SYW armies.

One observation is that the common images of blinds in Too Fat Lardies show fairly large sheets of paper more or less attractively displayed. Having though about the matter a bit, and looked at these lovely examples by Steven Thomas, I think that we can have a board with quite a few blinds on it without having it look like I accidentally spilled my paper crafts on the table.

So, purely on speculation, what do we need in the way of preconditions and rules to make blinds works (and I need a better name for them, too).

Well, we need to not actually know the enemy OB. If I know what forces the enemy starts with, eventually I will know if I have found them all, or how much I have to worry about them. To get the full effect of Mars-La-Tour on Bazaine, for example, you need the possibility to exist that in fact the whole German army is moving into his line of march. The latest version of Volley and Bayonet includes the Road to Glory subsystem for dealing with uncertain OB, and I will look at it in more detail in a later post.

To continue the uncertainty, I think you need to have some way to keep blinds in play. If they are not ugly, then as units -- or empty blinds -- are revealed there should be a way to bring them back. This could include splitting existing blinds into two, allowing units that have moved from sight to re-blind, and of course having blinds return on entry points as possible re-enforcements.

We need to decide what can be in a blind. Since the basic maneuver unit will be a division, clearly a blind can contain a division. It can also, of course, contain nothing. I suppose it should be able to contain detached cavalry regiments for doing recon (and what rules shall we have for detachments - something for another post).

We need rules for revealing blinds. Should all reveals be complete, or should I be able to reveal one stand (which may be all that is there) to force an enemy blind to reveal?

We need rules to keep unrevealed blinds out of sight of each other. Blinds should not be a free recon unit.

Not a huge list I think. Should be interesting.

Random and uncertain are not the same thing

"No calculation of space and time guarantees victory in this realm of chance, mistakes and disappointments. Uncertainty and the danger of failure accompany every step toward the goal ... In war, everything is uncertain."

...Helmuth vol Moltke, 1869 Instructions, quoted in Hughes, Moltke on the Art of War.

Who are we to argue with the master? However we are not fighting a war, we are playing a game. One of our objectives is that the game be fun; and one of the things that can suck fun out of a game is frustration.

This may seem odd -- after all at some level everything that gives an opponent a chance to win a game frustrates our desire to win it; in this respect the source of uncertainty hardly matters -- uncertainty is just another frustration.

I believe, however, that there are two kinds of uncertainty. The simplest form of uncertainty is simply not to know the situation; in an ideal game, I might have no idea of the enemy is unless I send out reconnaissance. I send out my cavalry -- or not. I am surprised -- or not. The enemy frustrates my intention -- or not. This is perfectly legitimate, and for people who ought to play wargames in the first place quite tolerable. You pulled one over on me, good for you.

In a typical wargame, on the other hand, I know exactly where my enemy is and exactly where my units are. I know where their commander is, and I know there is exactly an 86% chance that they will follow him to a successful attack. I know that there is one chance in 36 that they will do something utterly ridiculous, and in fact on 1/6th of those occasions they will simply march off the table. In fact, I know far too much about what may or may not be about to occur. All that I don't know is what the dice will decide. And when I roll 12 followed by one, I am frustrated; I am not uncertain or apprehensive (which are reasonable emotions to feel in a game with an opponent) -- I am just plain annoyed. Of course I should not have started my attack knowing how it would come out. But this sort of thing makes the dice the main adversary.

Now there is friction in war, grit in the machine, time and chance happen to all. When Steinmetz took over control of VIII corps and drove it to fruitless slaughter at Gravelotte, von Moltke was profoundly frustrated. A very pleasant exercise in frustration can be enjoyed by playing a multi-player game. People are intensely frustrating - but this is a proper form of frustration. Rolling a bungle with the VIII corps commander followed by an uncontrolled advance models the effect. But it does not feel right; it is those damn dice, it is my rolling, it is Fortuna Imperitix Mundi.

Humans personify bad luck. Good gamers work not to, but no one is immune to it. In this design I want to minimize the extent to which I resort to random frustration to model imperfect knowledge and control by the players.

Confusion, Uncertainty and Frustration

There are basically three approaches that have commonly been used in wargame rules to place limits over the ability of a player to respond to the situation as he sees it on the table. This is critical, since in an unrefereed miniatures game a player has far more information than would be available to any general.

One way is to tie the player to a intent expressed prior to the next round of enemy action being known. This is often linked to some sort of simultaneous resolution. Charge! and Command Decision are examples of this approach.

A second is to impose uncertainty about the ability to act on the commander's intent, by forcing a roll to determine if, and to what degree, a unit can act. Black Powder, Blitzkrieg Commander, Warmaster and Hearts of Tin take various approaches to this.

A third is to vary the sequence of action, by using cards to select the order in which units act, or what they can do.

Some attack the problem indirectly, for example by limiting what can be done outside of a certain radius of a command stand; or push the solution somewhere else by constraining movement or combat.

Most rules mix these in some way - 1870, for example, uses command radius, order chits, and random chance of activation.

All of these have their virtues. And to cover a situation like Mars-La-Tour where so much depended on Prussian bluff and French passivity, you need something.

So, I have listed some great rules that I have played with pleasure. Why don't I just steal the best bits and get on with it?

In the next post, I will vent my concerns about random activation and player frustration.

Stand Sizes, redux

Number two. Beauty being everything (or we might as well play with cardboard counters) it occurs to me that while a 30mm frontage looks OK as a march column, 40mm looks quite naff especially where everything else is 30mm (except command stands, but they don't count).

I was just going to edit the old post, but since this is a log...

Cavalry Regiment, both sides: 2 figures - 5-600 horse, 30mm x 30mm
1/3 of a Brigade - 2 battalions, 2000 men, German: 6 figures, 30mm x 30mm
Infantry Regiment - 2000 men, French: 6 figures, 30mm x 30mm
Guns (2 batteries, 12 guns): 1 gun and crew 30mm x 30mm or 40mm depending on model size.

That will make a French brigade 2 infantry stands, and a German 3.

A plan for basing - number one

I wonder how many of these I will work through.

Anyway, assuming 10mm figures and with the first dimension the stand front:

Cavalry Regiment, both sides: 2 figures, 30mm x 30mm
Infantry Regiment, German: 8 figures, 40mm x 30mm
Infantry Regiment, French: 6 figures, 30mm x 30mm
Guns (2 batteries): 1 gun and crew 30mm x 30mm or 40mm depending on model size.

Division command will have to carry status information, so perhaps 40mm square or circle with a small command diorama and space for markers. Likewise for Corps and Army, perhaps with different shapes.

I am also considering "markers stand" to provide spacing for march columns (a wagon and marching troops on say a 30mm x 60mm stand).

So what about Cavalry

Dramatic uniforms, moments of glory, but basically cameo appearances in the real drama of the battles.

Still, if we want to put put the building blocks of a Prussian infantry division, we have to represent the cavalry regiment - 5 to 6 hundred sabers.

As a side note it is truly amazing how many books go onto loving detail about the headcount of a French or Prussian infantry company, but breeze past a cavalry squadron as if everyone knows what that is.

Cavalry divisions seem more variable - 2 brigades generally, plus a battery or two of horse artillery. Sometime three regiments to the Brigade, sometimes two. Sometimes even three brigades. Often of different "types" within the same brigade.

Anyway, I am inclined to represent cavalry regiments as regiments.

And a stand represents....

That's an interesting question in a lot of ways. There are a lot of things that make the wargamer's idealized OBs and TOEs a matter of fiction. But at the same time it is a fiction we must embrace. Unlike computer games, or boardgames, or even the original Kriegspiel where units can be subdivided as much a suits, miniatures have a certain size that makes it hard to break down units beyond a minimum granularity.

But so be it. I have already pretty much decided that the lowest level of commander for a multi-player game is the corps commander, and in 1870 for both armies the building blocks of corps are divisions. The way they corps are built is very different between the French and Prussian armies, but that is another post. I'll set the Cavalry divisions aside for now as well.

On the French side, a "typical" infantry division is more or less 2 brigades, each of 2 regiments of line (with the 1st brigade having a battalion of Chasseurs as well a bonus) plus 2 batteries of field guns and a battery of Mitrailleuse. Since a French battalion is 750 men at full strength, that gives line regiments of 2250, and brigades of 4500-5250.

More of less, give and take. Units can be below strength to varying degrees, battalions can be detached, battalions can be attached -- all of these things I may want, or need, to consider at some point.

Before I get into the German formations, I shoudl make it clear that I am starting with the Prussian practice, before looking at the rest of the North German Confederation, and then at the various South German allied states. Although the Prussians were more-or-less the models the other states were moving toward, in 1870 the integration was not complete and German practice in general is not exactly always the Prussian model.

Anyway...

The Prussian infantry division is a bit more complicated. It likewise has 2 brigades each of 3 regiments. The regiments, however, are made of 3 x 1000 man battalions. The Brigade therefore is 6000 men at full strength. While each French division has a battalion of Chasseurs, Prussian Jaegers are a corps asset, so one may or may not be attached to a division.

The artillery firepower is far greater, with 2 batteries of Krupp lights, and 2 of heavies. In addition, a 600-saber regiment of cavalry was integrated with the division.

This means our Prussian division at paper bayonet strength is nearly 25% larger than its French opposite number, setting aside supporting arms.

So, how to represent this?

There are several ways to go, each with it's own advantages and disadvantages.

The simplest is "a stand is a division" - nice big stand, all types of figure on it.

For the next level there is a split. We can take a uniform stand size and figure count and say "this is so many thousand men" -- So if we take 3000 per stand, a Prussian division gets 4, a French 3 and Bob's your uncle.

The problem with this is that it cannot map any historical designation by the stand for both sides. At a stand equals 3000, each stand lines up nicely with a Prussian regiment, but a French brigade is a stand-and-a-half. At 2000 men each, the French Regiments sort out nicely, but a Prussian regiment becomes a stand-and-a -half.

Is that a problem? If we are just talking about the Division and the stands are just representing states and formations within it, this should be no worse than the common practice or representing a lace wars battalion as several stands and ignoring the platoon or company organization within it.

You can tell I am waffling on this issue.

The alternative is to have each stand represent a fixed formation - say a French or Prussian regiment -- and have the difference in size represent in the base size and factors. Then I can say "That stand is the 2nd Turco Regiment, 2nd Brigade, 3rd Division." This is especially nice for the French, with their fancy uniforms.

At the moment, I am not going to worry about the Brigades of the Army of the Loire, which paired a Regiment De Marche with a regiment of Guarde National Mobiles in each of its brigades.

Except perhaps to consider it simplest to break a division up into either 4-6 2000 man stands or 3-4 3000 man stands.

the larger number reduces the number of stands, making it easier to make the time objective. The smaller lines up with the French regiments for the sake of the pretty uniforms, and make the stand or that pesky 600-man attached cavalry regiment a bit more beefy in its figure count.

In the next post, I will try to fit cavalry into this picture.

update: Ive been kicking this around a lot.  Here's the July 2012 iteration.

Implications for Scale

So what do the objectives apply for scale?

The maps in Ascoli's Day of Battle cover an area of (roughly) 9 by 6.5 miles. The short dimension is the more constrained. Converting to metric, this gives a minimum of about 86m per table centimeter. One hundred meters per centimeter gives a nice, round number on the safe side.

After a few years of experiment I have found that the smallest base size that works easily for me is 30mm square. I could end up with larger bases, but 30mm on the smallest dimension will be a basic guide.

Day length is interesting. It is easy for a North American to forget how far north European cities are. While the action proper was about 12 hours, a dawn-to-dusk struggle could easily run to 15-16 hours.

Focusing on 12 hours, however, with a six hour duration objective, we have to be able to resolve 2 hours of action each hour. At the peak, something like 20 division(ish) French units were involved. For the "Gravelotte-St Privat" battle the French Numbers are similar while the Germans have something like 15 larger and more complex divisions. At 20 "command units" a side, we would get something like:

• If a turn represents one hour, it must last 30 real minutes. Assuming movement is not simultaneous, time is shared evenly, and a two player game, that gives 15 minutes a side or 45 seconds a division.
• If the turn represents two hours, we have a minute and a half per divisions.

So, if we say a division is 5-6 stands (cavalry divisions are quite different of course).

• 4 infantry regiments (in two brigades)
• 1 double battery
• for the Prussians (with small variation for its allies) a second double battery and a cavalry regiment.
  

how long should such an entity take a normal player to move? Personally I am quite quick about such things but that varies a lot and the "not frustrating" objective suggests that I should not be unreasonable.

On the other hand a slow player with a chess timer could simulate Bazaine very well indeed.

Of course, a formation could be a deal simpler -- one stand per division, one per brigade, guns factored in or out. But that would be another post.

Considering wargame rules for the Franco Prussian War

Every project needs a well defined object. Here is mine:

To produce a set of wargames rules with which I can:

• Refight the battle of Mars-La-Tour
  
• as a fun 2 to 8 player game
  
• on a 6 foot by 4 foot table
• using Pendraken 10mm miniatures
• in under 6 hours

The rules, of course, must be usable for smaller actions in proportionately less time and space -- but not battles where the size of one force or the other falls below the basic resolution of units.

So much for the positive. There are a few negative objectives as well:

• The game must not be "fiddly." My fingers are arthritic and my vision is blurring. This means that base sizes must be reasonably large and small status and tracking markers must not be too numerous or tiny.
• The rules must not require specialized terrain boards -- they must work with more-or-less ordinary wargames terrain, preferably from my existing stock.
• No rosters. Status tracking displays I can build and put on the table or fine, but I dislike paper checklists.
• The game must not be frustrating. A game must be challenging, but the player must believe that he wins or loses based on his own decisions most of all.
  

It is also important that the rules follow as much as possible a proper point of view. It is a good general guideline for a wargame that an Army commander should control corps and know where his divisions are, and that a corps commander shoudl command divisions and know where his brigades are. While details below that level can be technically very interesting, they do not belong at this level of games. There are many tactical games that address that level very well indeed.
