@Mr_NutterButter I think it's that Mario Party is usually seen as a game of luck, not of skill. So when one guy always gets lucky enough to win it feels worse than a guy being better at the game.
I think the last time i played with any of them was a few years ago and I won by like 7 stars lol.
@Mr_NutterButter also makes me think of scrabble, the last time I played that with someone other than my mom I beat the guy in second place by 150 points and the guy in third crashed out because I played "ax" which he didn't think was a word and lost the challenge
