And you thought you had a lot of video games.

According to PC Magazine, a New York man named Michael Thomasson recently achieved the ultimate milestone as a video game collector: the world record for largest video game collection. The title has been made official in a special video game centric edition of the 2014 Guinness Book of World Records, which includes a two-page spread on Thomasson and his behemoth gaming vault. The book, officially titled Guinness World Records Gamer’s Edition 2014, is now available and can be found at the Guinness World Records website.

The book includes a wide range of video game oriented records, from record completion times for some of the industry’s all-time favorite games to eye-opening profiles on a few talented people who actually make a living playing video games. However, while the fastest play-through of Batman: Arkham City is probably a cool record for a gamer to have the bragging rights to, Thomasson’s record is arguably the crown jewel of the book and the envy of every other gamer on the planet.

Why should gamers be jealous of Thomasson? Quite simply, his collection knows no bounds in the video game world. He has games from every generation of the medium, from the compact discs used with today’s consoles to the cartridge, laser discs, and tapes of gaming’s past. When Guinness locked Thomasson’s record into place for the publication of their book, the collector had about 10,607 items. Now, Thomasson contends that he has amassed a gaming stockpile with more than 11,000 gaming titles.

While Thomasson’s collection of games is vast and valuable, doubtlessly including its fair share of rare and sought after titles, it would be little good if he didn’t have any way to play all of those games. In addition to his thousands of titles, Thomasson also owns just about every video game console known to man, from Microsoft’s Xboxes to Sony’s Playstations, all the way to rare and (rightfully) forgotten console attempts from the likes of Casio and Apple.

A lifelong console player and a fan of all things video games, Thomasson doesn’t actually get to play his games that much these days. He’s a husband, a father of a young child, and a professor of video game design, history, and animation at Canisius College. Still, while the collector gets about three hours of play time in during any given week, he’s continuing to follow the collecting routine he’s had going for years: two new games a day on a $3,000 a year budget. The total value of his collection? Somewhere between $700,000 and $800,000, and growing.
