lol kotOR is a single player game. What do you have to care if your neighbor uses cheats?
Nothing forces you to use cheats.
I don't see the point in removing that option from those who want some cheats and penalize everyone just because you don't want to cheat...If you don't want cheats, just don't use them.
I like to mess around with cheats after my fist playthrough and try things I wouldn't try in a normal game (such as those somewhat useless force powers), not to mention that cheats are extremely useful when you mod the game.
