I play this one a bit actually, Mount and Blade regular though is much simpler.
A couple tips, one, when ur aiming your sword to swing at someone from a horse, u either have to be right next to them, or dont swing right at the ground, that was the most annoying thing for me when i first played this game.  Second, cheat bro, having all the cash and best armor and weapons makes the game alot more enjoyable, first time around its nice to go around the map as a poor person doing this quest and that, but second or third play thru, it gets really boring having the crappy armor and getting ass raped by the computers higher overpowered units.
