I don't, it's not fun for me, save for teh occational god-mode thing after i've beaten the game without cheating.
I have nothing against people who cheat in single player games, if they're having fun doing it then fair enough, why would i care.
I hate people who cheat in multiplayer though, it's only pathetic retards who either enjoys griefing, or honestly just likes to win so much, that they don't care whether they actually won, or cheated their way to victory, like people who will feel proud by winning a fist-fight against a 10 year old.
