I collect classic gaming posters and magazines. I have a decent amount of old Nintendo Power magazines from the NES & SNES days as well as a bunch from the Gamecube era. Also a few other random gaming magazines like Electronic Gaming Monthly, Tips & Tricks, and Official Playstation Magazine among others. I also have a long run of the current running Game Informer, but it only stretches back to the beginning of the last-gen (PS2, XBox, Gamecube, GBA). I'd LOVE to get my hands on the first few issues of Nintendo Power, and I'd LOVE to get my hands on Sega Vision and Official Sega Dreamcast Magazines.
I also have quite a few gaming posters around my house including Super Mario Bros. 1, The Legend of Zelda: Ocarina of Time, Mega Man X, Metroid: Prime, Super Mario Galaxy, Time Crisis, Sega Master System, WCW Thunder, Resident Evil, Gears of War, Halo, and others. They're mixed in with a ton of Marvel & DC Comics posters and metal band posters.
And finally have a small collection of gaming books. I have an awesome, huge, informative, fully-color book called "High Score! The Illustrated History of Electronic Games"

I also have this really cool book that is a great reference for collectors. The "2007 Video Game Price Guide". Obviously the prices in the price guide aren't gonna be accurate, but it's the most complete, printed in book form list of retro games you will find:

I also have a bunch of different code books for different eras. I have one for the PSX/Saturn/N64/GBC/Dreamcast era. I have one for N64/Dreamcast/PS2/XBox/Gamecube/GBA era. I have one for PS2/XBox/Gamecube/GBA. And I have one for PS2/PS3/Wii/XBox 360/DS/PSP era. Go any further back and I have to track down individual magazine issues or books that are only on an individual console. I will eventually get them, I just haven't got to them yet.
