His collection includes plenty of rare and hard-to-find stuff, like this Mexican copy of "FIFA 15" for the Nintendo Wii.
According to Monteiro, "FIFA 15" on Nintendo Wii was only released in Mexico — which makes it part of the North American game library, even though it may not have launched officially in the United States.
He says he imported the game from Mexico for the sake of his collection.
And yes, as you might imagine, Monteiro also has a full North American collection of Sega Game Gear games.
And a complete collection of Sega Genesis games, and a complete collection of Sega Dreamcast games. That's a lot of Sega games!
No completionist video game library would be truly complete without the Phillips CD-i games starring Super Mario and Link — and yes, Monteiro has both of those:
"Hotel Mario" and "Zelda's Adventure" are two of the few Phillips CD-i games ever made, and they're especially notable for featuring Nintendo's two most important franchises: "Super Mario" and "The Legend of Zelda."
They're also especially notable for being bad games.
