Well that this is a game is out of the question.
But to me it's a lot more too.
I admit, i've never enjoyed history so much till when i starded play games about that.
these are simulations as well and those games we play now are somewhat "primitive" they could improve furhter on and i belive this is now "the frontier".
Concerning about two handed swords, i've been for a little time a historycal reenactor and (for fun) i've played both two hand and one hand sword vs an adversary, and it seem to me that the one with the two hand weapon haved more chances of hitting the target. (but even more to be hit).
Also if the two adversary swords get in contact there is always the chance that one sword gets broke, and it actually had happen, which one? the bigger or the smaller?
I would like to know why to be 100% historical we can't have any two hander units?
