I think I have the largest collection of anyone on here. Check my signature. Not listed: Over 300 Atari 2600 games, among other things. I only have so much room lol, so many games are in boxes. Also not listed: Colecovision, a few Intellivisions, Jaguars, 3DOs, CDis, Atari Lynx, a few Game.com games (No f'n clue where they went, I'm guessing they're gone forever at this point), Atari 5200 and Atari 7800 games, some Sega Genesis, a few NES games, around 200 or so games that I attempted to list but of which IGN had no listing... all around, I have about 1,000 more games then I have listed.
No Emulators. No bootlegs (well, some bootlegs but I'm not counting those), no backups. I'll try to figure out the URL to my collection pictures.
ETA: A few people here might have more games then I do but of the (last count) 2700 games I own, I count no duplicates. Count the duplicates, and I'm sitting at around 3000 or so.
Random stuff. N64, X-Box, and PS2. Photos taken in October. Since then, my PS2 collection has doubled. Disregard the Tales from the Crypt videos, and instead notice the two of the 26 ROBs I own (of which only four are working, go figure. The two pictured are of the 'broken' varity).
Gamecube collection, with one of my six Virtual Boy's looking on in menacing fasion.
My NES collection. My pride and joy. Every game works, though I must concede that not all of them are in what I would call mint condition. I spent the better part of a weekend once trying to figure out how to get rid of the... ugh... mold that was inside a copy of crappy ass Barbie by Mattel that I bought at a garage sale for a dollar.
A few display boxes that were donated to my collection by my pals at Game Crazy. Note the sealed copy of Cookie Monster Munch for the Atari 2600 that I found in a freebie box at a garage sale.
More boxes, plus a bunch of Marios that I found at a (you guessed it) Garage sale for five cents each. I'm convinced they are the real my car keys keep disappearing.
Random NES bootlegs and multicarts, most of which I bought from a flea market in Mexico. A few are unworking. Crimebusters is neither a bootleg nor a multicart. It's very valuable and hard to find. I think I paid $20 or so for it. The orgins of the game are still somewhat a mystery. It's a neat little gun game.
A few of my Gameboy Advance games. Once again, note that these photos were taken in October and don't accurately reflect the amount of games I own for it. Too soon to tell if any of these will be collectable in the future, but I do think 90% of them are pretty good games.
A bunch of random games for random machines. Looks like a few Genesis games, a few Atari games, a few Intellivision games, a few Coleco games, a few Jaguar games, a few Arcadia games, and a few Sega Master System games. I appologize that it was unorganized. I had just started rearranging my Game Room. I also seemed to forget to take a picture of my SNES collection. D'oh!
A very hard to come by Version 17 Gamecube Kiosk disc, complete with the demo drums in their original brace. I've turned down offers over $200+ for them.
A few more Gamecube Kiosks.
I hope y'all enjoyed a trip into my game room.
