Someone made a comment the other day that made me think, "Hey, if we can do this, you practically create half again the available combat scenarios in cRPG".
How difficult would it be to mirror the animations and models so that players can choose to be either right or left handed? Just like in boxing, a fighter will have to adjust in a duel when coming up against a Left-handed 1 hander as opposed to a Right-handed 1 hander.
