I suggest you tie him down, threaten the well being of him and his family, and force him to play. Then he'll learn to like it! Bwa ha ha!!!
I feel sorry for him. As for my friends, one plays mainly RPGs, and though he doesn't have a system, PS2 would probably his first choice. He plays SSBM with us though, but refuses to play Monkey Ball because we always beat him using Baby. My other just plays games on his PC, but will play Monkey Ball or whatever else we've got. He loves Sonic Adventure Battle 2. One owns an Xbox, but always says that he like PS2 and Gamecube just as much, and the other one owns a PS2 and Gamecube, and he'll play Halo a bit if the Xbox guy brings it. Those're the dudes I play video games with, so there was never any reason why we should debate.
