Cheating in a single player game is ok I suppose.
Cheating in mmos is ok if you're just screwing around and messing with people.
Cheating in a video game is sort of pointless unless your just screwing around, I mean what the point of playing the game if you're just going to opt out of playing the game by cheating.
Now cheating on something like Gaia though is theft and its far more entertaining to me than the actual game so cheating makes since.
