I have to say I'm with the varied interests category as well.. Here's a short list of games I've been playing at one point or another:
Arcade: Tekken, Soul Calibur, any variation of Marvel/Capcom/SNK, DDR, Guitar/Percussion Freak
Board Games: Chess, Scrabble, Monopoly!
Card Games: Poker, Magic: The Gathering, Legend of the Five Rings, heck even Pokemon and Yugi-Oh!
First Person Shooters: Doom and Half-Life titles
Role Playing Games: Resident Evil, Final Fantasy, Diablo, Neverwinter Nights, Dungeon Siege, Ragnarok (flunked a semester playing this MMORPG so I forbade myself from ever playing one again)
Strategy Games: Civ is the only turn-based game I play as I grew up on RTS games from both Command & Conquer and Warcraft titles.
