And gosh, he sure does have several beautiful walls of games. You can check them out in a video Guinness posted to YouTube.
Those walls include complete collections for consoles like the Sony's PS2 and PS3, Microsoft's Xbox and Xbox 360, the Nintendo Wii, Sega Dreamcast and several others. The 10-minute video merits multiple viewings so you can spot some of the treasures, with plenty of chunky collector's editions and more than 100 systems (so you can play every game he owns).
