What makes a 'good' game?

[Ultimecia]

I tried to play the RPGs, believe me. But all I managed to do was to make horrible puns while playing. Maybe I'll have a friend to play while I'm watching, I got a die-hard Nintendo fanboy as a friend and he IS threating me with Mario RPG anyway. My friends like to play single-player stuff with me because of my jokes (more than once my former roommate had to stop playing because she was laughing so hard she couldn't hold the controller. And I STILL laugh when I recall some of those events).
Sports.... I'm not much fan of the genre, and racing isn't one of my favorites unless you can obliterate your opponent's vehicle, like Road Rash and MegaRace.
