The idea of a girlfriend is a good one! It could add alot more depth to the game, in many different ways. Maybe if you are cheating on your girlfriend, you would have to fight her, or you could see her and the girl you cheated with fight. Haha now that would be interesting. It could have a suspicions bar which increases the more you cheat on your girlfriend, and when it gets full, she will find out. Hey you might even be able to get "lucky" in the game (improvised of course). Oh the posibilities.
