Check Out The World’s Largest Video Game Collection

There is a thin line between a hoarder and a game collector, and Antonio Monteiro walks it every day.

The Texas man got the Guinness World Record for the largest video game collection: 20,139 (as of March 28).

Monteiro’s library, which has been developing since he was a child, features games for a second- to eighth-generation consoles—as well as 100-plus gadgets on which to play all of them.

For a dim idea of scale, his stock includes:

• More than 1,000 PlayStation 1 titles
• Complete PlayStation 2 collection (North America)
• Complete PlayStation 3 collection (North America)
• More than 900 PlayStation 4 titles
• Every PS Vita game released to date (North America)
• Complete PSP collection (North America)
• Complete Xbox collection (North America)
• Complete Xbox 360 collection (North America)
• More than 500 Xbox One titles
• Complete Wii U collection (North America)
• Complete GameCube collection (North America)
• Complete Wii collection (North America)

• 118 Nintendo Switch titles
• Turbografx games
• Super Famicom games (the equivalent of Super Nintendo for Japan/Europe)
• Complete Sega Dreamcast collection (North America)
• Complete 32X collection
• Complete Atari Jaguar System collection (North America)
• Complete Atari Lynx retail collection (North America)
• Complete SEGA CD collection (North America)
• Japanese Saturn games

• Japanese Dreamcast games
• Complete Game Boy collection (North America)
• Complete Game Boy Color collection (North America)
• Complete Game Boy Advance collection (North America)
• More than 1,100 Nintendo DS titles
• Every Neo Geo Pocket game released in North America
• Nintendo 64 collection
• Atari and Gauge games
• SEGA PICO titles
• Complete NES collection ((North America)—including unlicensed titles

The collection is so big (how big is it?) that it took eight days to count before Guinness could confirm the record.

“I’m really excited to be finally sharing this with the world,” Monteiro, who clearly takes great pride in his highly curated selection, said in a statement.

Of his 20,139, however, “Castlevania IV”—a 1991 platform game from Konami, described by Monteiro as a “masterpiece”—is his personal choice.

There are many duds, for sure, as well as many “unusual” pieces, like the “Max Basic Rifle Marksmanship Program,” released by Nintendo exclusively to the U.S. Military for shooting practice and never sold to the public.

Monteiro—whose job and bank account balance was not shown—also owns a comprehensive collection of Nintendo 64DD games, published only in Japan; rare Sega Game Gear title “CJ the Elephant”; and a series of informative Sega Dreamcast games such as “Timeless Math.”
