The original Game Boy, first released all the way back in 1989, pioneered the handheld gaming market. Sure, little novelties like the Game & Watch existed before it, but the Game Boy was truly the first "portable console", allowing gamers to build up a collection of games that they could swap out at-will. A lot of now classic series and gaming conventions first saw the light of day on the Game Boy, and here are the best of the best of them.
We may as well start off with the most ubiquitous Game Boy game out there. The Russian-developed endless puzzler actually came bundled with the Game Boy for its US launch, and proved to be a hopelessly addictive time waster. It was also the very first Game Boy game to make use of the link cable, allowing two players to play competitively against one another.
