Michael Thomasson, owner of the world's largest unique video game collection, is putting his beloved library on the market. In 2012, Thomasson received the Guinness World Record for this collection of 10,607 unique games, and since then, has added to it. It's now about 11,000 games. The Guinness Certificate will be sold alongside the collection. 

Thomasson built up his massive collection through serious hunting — but managing seven gaming stores helps too. Thomasson also manages Good Deal Games' online market, and has since 1998. This allows him to snag the best games for himself and has resulted in him owning about 2,600 games in their original packaging. 

Family obligations pushed him to sell the collection all at once, but he plans to keep collecting after it's sold. In 1998, he sold his collection to pay for his wedding and then built it all up again. He said, "I love games and they are pivotal part of my identity. I will continue to champion them. I've sold my collection many times in the past and still managed to capture Guinness' attention, and it is entirely possible that I may again." So in twenty more years, we can probably expect to see the collection hit the market again. 

Right now, the price is at $50,000, but the reserve has not yet been met. If you want to own a lot of games, you can bid here
