This issue is, and forever will be never-ending. I myself am torn between the 2 sides. On one hand, cheating is cheating, manipulation of the game = cheating. On the other hand, I used to play modded custom games constantly. It was pretty cool to just go in, and throw rockets instead of grenades, fly a hog, or even just a turret. The guys I played with hated cheating in matchmaking, they never did it. Just hung out and had fun in custom games.
Then superbouncing to me is definately no where as bad. Nor button glitching. These are defects in the game, that Bungie is aware of, and they are used numerous times a day, even at the mlg tourneys. TO me they are not an unfair advantage, because ANYONE can do them if they practice them. No one just picks up the game and can do them, just like sports in real life, or anything, you have to practice to get good at it. And Action Replay definately should be legal, thats no where close to being as bad, once again, it enhances game ply by offering many custom games, it adds a certain spice to the video's in montages. Just my oppinion, cant do it cuz of the honorr code, but yea.
