I was addicted to playing Mario Kart with my friend Ben when I was up at Humboldt for eight days. I got pretty good at it. I always played Koopa Troopa on a bike. I kicked ass at 100cc. So fun. =]
Yeah those are all bad games. If you HAVE to pick one I guess godfather, but you should really just pick something better. Check out http://metacritic.com and pick something with a good score.
