2. Crazy Cheat Codes
Cheat codes are like antiques these days, since the advent of Achievements/Trophies there really isn't much a developer can do about it either. There is so much fun to be had with old school GTA cheats, pedestrian attacking everyone was like creating a whole new apocalypse game once the 500 hours of murder death rampages got old. However, with great cheats, comes great confusion: Remember the very last mission on GTA 3? At the dam you have to save that really annoying girl from the Cartel? Well I had forgotten that I had 'Pedestrians attack' enabled during that mission and when the camera cuts to her being held hostage you should have a certain amount of time to kill the Cartel and save her. As soon as the cut scene finished the Cartel guy would kill her and I would get the 'Mission Fail' message. It took me a good while to work out that this wasn't the HARDEST end game ever and was simply a result of me being a cheating bastard. Or an idiot depending on your stance. Either way, my point is don't expect crazy cheat codes outside the normal ones you got in GTA IV.
