I really don't understand why people even bother cheating online.
I've not come across any yet in Mario Kart (or any that I've noticed) but what's so fun about winning because you cheated? Surely because you're good is more satisfying?
I'm trying to figure out the same thing. It's not like you get anything by cheating to win, and you aren't showing off much, cause nobody can see what you're doing unless you're near them and most of the time it doesn't last for more than a few rounds because everyone rages quits cause everyone's savvy to the nonsense. Even if "showing off" is you being 20 years ahead of everyone, it's just like "oh okay they were way up there" big whoop.
