I was at a friend's house the other day and he was playing a game on his computer. In the game, every single character you see is controlled by a person; cops, mayors, gun salesmen, etc.You can basically run around and do whatever you want: rob banks, steal, buy guns from other characters, etc. It looked really fun but I can't remember what it's called. I guess it's not a big game you buy in stores, my friend said it was made by normal people and you buy it online for $10. Does anyone know of this game?
