when people cheat at single player games it is sometimes because they enjoy 'being God' for a while and doing things that they ordinarilly wouldn't be able to for fun. Sometimes its because they find the game too difficult to complete and simply want the storyline they are following to continue, rather then spend two hours trying to jump to a tricky platform.
However when people cheat at onnline multi-player games it is because they suck. I'm not sure how you can cheat at SWG, but I was playing Call of Duty the other day and unloaded a full round from a BAR into the back of some campers head (a guy who bunny hopped constantly when he wasn't camping behind a doorway) and he didn't die. One head shot from any gun kills you in that game, and about three to four shots from a bar will kill you anyway. I just thought to myself why do gimps like him play onnline? Then I asked him. He got angry and said moaning that the point of the game was winning, and if I was into realism mods I should appreciate that he was taking the game like a real war by trying to win by whatever was necessary. I realised he spoke like a gimp as well, as did the others on the server, and we kicked him.
This has nothing to do with SWG, but I just hate it when people cheat with other people. I don't care that people cheat with themselves on other games where they play single player, but when people cheat with others at games you can just tell what sort of person they are usually like from the example I used above.
