I don't care about playing poorly or not...it's the game itself, if it's too casual of a mode, it bores the hell out of me.
I can lay in bed and play Peggle all night long on my tablet, but games like Battlefield, Halo, etc...I can't enjoy their casual modes...e.g., rocket race, grifball, etc.
Silly game modes bore the hell out of me, they're not the least bit entertaining. I need substance when I game, an objective, a need to want to win, when it's a pvp game.
Hell, even on the NHL Arcade game that's 3v3 on Xbox Live Arcade, I disable the powerups, and make it be just normal pond hockey, it's fun as hell, but the moment the powerups come on...I get bored.
I do enjoy Mario Kart though
