Video Games
for my money, videos games don't get much sweeter than Resident Evil 4. I love ALL the RE games, but 4 was, hands down, the best.
I recently picked up Guitar Hero 3: Legends of Rock, and that's pretty darned cool as well.
I'm a huge sucker for any and all games in the Zelda franchise, and all of the Mario Kart games. But I enjoy just about anything that can be played on my Nintendo Wii. :D
