The thing i most hate in STW is massive stacks trained by computer. You know, after killing the enemy general you just simply cutting their reinforcements down, waiting for them to apporach... It gets boring.

And dont think time limit is unrealistic: Although units already in close combat stops fighting after time limit sounds a bit stupid, in history there are lots of battles was ended due to time limit. In fact, lots of other weird things happens on real battlefield: Like fighters dont recognize their mates and attacking them, or a general gets hit at the beginning of battle... And even more exantric tricks like spies, lies...

Anyway i will stick with the idea of having time limit ^^
