Racing is #1, mostly because I am a racing fanatic. I like just about every kind of racing game wether it is arcade or sim. Sports Car mixed class endurance is my favorite type of real world racing. RPG's are a very close second. The Suikoden series is my favorite series of RPG's. I love a good story with good characterization but I also love many of the game play mechanics of RPGs. Most, sadly, are missing from modern day rpg's I would also add "arcade shmups" but sadly they are few and far between today. Resogun scratches that itch somewhat, and is fantastic in its own right, but still is not the same thing. Mars Matrix is one of the shmups I remember from my local arcade that I would cash out 20's to play.
