my card game of choice would be YuGiOh.
played that back in high school, still have that crap somewhere.
fun game, personally prefer it to MTG or pokemon, though all are at least fun.
honestly, i think the reason to play one game over the other isn't the game itself, but the people who like it.
my roommate plays MTG and works at a game shop that sells that stuff, and all the other guys are total toolbags.
on the flipside though, yugioh...
