I think this applies to single player only, at least for me, but do any of you like to use cheat codes sometimes? I use to think it would take away from the game, but some of the codes do make different games more fun. I use to play Grand Theft Auto on the original Xbox, and that version was my favorite simply because of the codes. I loved using the vehicles I could never unlock and my favorite was the jetpack! I'd fly everywhere with that thing.
