grand theft auto IV is amazing. i still suck, but i've enough skill to now manipulate the controllers decently enough: i can steal cars; kick the crap out of innocent bystanders; & steal a car from cops while they're shooting at me.
i also ♥ katamari damacy. although the concept is simple enough, i am not so good at it -which sucks when the person you're playing with is getting 2-3x the needed growth of the katamari.
i'm anxious to try wii fit & play warioware: smooth moves while slightly inebriated.
