game and watch!
After the Game & Watch, the handheld development continued with the Game Boy, the Game Boy Pocket and Game Boy Color, each differing in minor aspects. The Game Boy, the best-selling handheld and second best-selling console of all time, continued for more than a decade until the release of the Game Boy Advance, featuring technical specifications similar to the SNES. The Game Boy Advance SP, a frontlit, flip-screen version, introduced a rechargeable, built-in battery, instead of using AA batteries like its predecessors. The Game Boy Micro was released in 2005, after the Nintendo DS's release, but did not sell as well as its predecessors.
