Just old gaming magazines, pretty much. And a few posters I have hanging around the man-cave.
My favorite gaming magazines being VideoGames and Computer Entertainment, EGM, and Retro Gamer.
I also collect comic books, big time, and some of them are gaming related. Like Captain N, Game Boy, God of War, Halo, Wolfenstein, Mega Man, and a few others. But it's not like it's a big chunk of my comic collection or anything.
