Well, Mount and Blade does not have cannons and muskets booming away spouting smoke and actually making the bodies move (I have never seen the ragdoll effect in M&B apart from when you kill a guy on a slope), and, as you say, 200 men; we are hoping for atleast 50 times that number in a single ETW battle.
I do wish that they'll hurry up and give the min. requirements soon.....
