Video Games
Grand Theft Auto. All of them. 1, 2, London, 3, Vice City, San Andreas, Liberty City Stories. Still waiting to pick up Vice City Stories, as it was just released for PS2.
Tetris is awesome, and Tetris/Dr. Mario for SNES was one of the best cartidges of all time.
Old School SNES RPGs like Final Fantasy II, Chrono Trigger, Palladin's Quest, and 7th Saga ate up many months (not just hours or days) of my young life.
Music
Gwar.
Metal, some hardcore, some punk, some radio rock. Very little country.
Totally random selection of rap and hip-hop, mostly directly related to NWA & Dr. Dre.
Ayunnoh, whatever sounds good at the time.
