Chievo's killed cheats. I thought GTAV did it well, if you use cheats you can't chievo. More than fair compromise and it's super disappointing how cheats are essentially non existent in most games nowadays. Chievo's killed Tips & Tricks magazine(kidding, sorta). It was always a treat as a kid to beat a game and then fuck around with all the cheats afterwards.
If you play on PC though:
Anyone remember Crackdown's Key's to the City? That was super super fun. More games should have done something similar.
