"Bad Guys" can be much more fun to play, but you have to let go of morals, which is quite hard to do sometimes. Even when what you're doing is not real, and has no bearing on anything what so ever. It's quite interesting really.

Ever played a game, where you get certain moral choices? You know, A) Give the kid back his bike B)Trade the bike back for the kid's hat C) Punch the kid, run off with his bike. 

You have to keep hitting that C option over and over. Sometimes doing that just feels wrong though, even though you know it's a game.

Get what I'm sayin'?
