This is my idea for a game. It's much like grand theft auto, but its mainly online multi-player. Basically your goal is to commit the most murders, and in the process become more wealthy, and so on. But the people you need to murder are the other people online.
Really it'd be more like pshome, but you're a criminal and can kill people anyway you can in real life. Take their money, bang their girl, and take off with the riches.
