What about interactive Tactical Combat ?

[Hullu]

I think a combat simulator would be a bad thing.

People would use it in MP to optimize and calculate odds. Sure, it's hard to get exact information about the enemy but it's doable with scout forces(attack, station a few cheap squads near the middle of map, with retreat order(s)). And once you have approximate information and approximate information abuot enemy orders - you could just brute force the 'perfect' tactic for yourself pitting the army you saw against your 'main army'. Definitely this would be a huge advantage compared to if you weren't using it.

Thus, I find combat simulator a bad thing.
