I'd honestly prefer that games not have cheats. Though I'm currently wishing I could get them to work on the Steam download of Far Cry 2, my farthest save game is worthless now since my character is stuck between an NPC and a fridge in the bar. I'd love to turn off clipping to just move away and be able to continue with that save game. Other than that, once I learn a cheat I'm often tempted to use it more often than not (like killall in oblivion, just to watch NPCs drop dead all around me.)
