@Dunkah, while I do not disagree that the idea of stacks can be fun or strategic, limited stacks do offer a problem that has been raised before. Which is that if 2UpT is the limit, then anything less than 2 units on a tile is not a "full unit". This is a valid arguement against limited stacking that does not exist really with Unlimited i.e Stacks of Doom. So basically the argument is having for example 4UpT does not add anything to game play as it is still 1UpT but each unit only compromises .25 of a unit. So having 3 units in 4UpT is just like having a damaged 1 unit.
Though the idea's of Forts where you can stack more than one unit to make a "hard defended area" is appealing to a defender, it really isnt to an attacker. And I believe it would cause unblance in a game and turn fluid battle lines where units make all the difference to a completely different result where you and your enemy will be lining up Forts on your borders for maximum defensive advantage, and this line will simply hold with niether side breaching it unless one side IS A LOT more powerful.
So while perhaps good in theory, and sounds like it would be fun, I do not believe the end result will be so.
