The Game Gear (ゲームギア) is a handheld video game console developed by Sega and released in late 1990 as a response to Nintendo's Game Boy handheld . It is a full colour console and was Sega's first attempt to compete in the handheld games market (the second being the Sega Nomad — a handheld Mega Drive). In South Korea it is known as the Handy Gam*Boy (핸디겜보이) and Handy Aladdin Boy (핸디알라딘보이).

After development of the Sega Saturn began, the Game Gear was retroactively given the codename Mercury.

Hardware

The Game Gear is a "portable" device which was designed to address problems with Nintendo's Game Boy. It is held lengthwise at the sides (preventing the cramping of hands which plagued Nintendo's system) and has a backlit, colour LCD screen, allowing for clearer and more vibrant visuals than its main rival.

Similarly to the Mega Drive, which at the time was Sega's main focus in the home console market, the Game Gear is derived from the earlier Sega Master System. Unlike the Mega Drive, however, the Game Gear is largely identical to the Master System, the major difference being a VDP capable of displaying palettes consisting of a wider variety of colors, and the playback of stereo sound. Game Gear games traditionally run at a smaller resolution too, although with a screen built similarly to televisions of the era, the Game Gear is fully capable of playing games in higher resolutions.

Like the Master System, the Game Gear features a D-Pad and two buttons, and , but also adds a third,  START . This is one button short of a Game Boy.

Unfortunately, due to technical limitations of the era, the Game Gear demands six AA batteries to be played on the go, of which the fluorescent backlight on the LCD screen will eat through in three to five hours (though a battery pack provides longer playtime). Furthermore, the system gives off more heat than the Game Boy, often leading to "sweaty palms" after prolonged use. The system was also considered not to be very "portable" - its bulky size means it does not fit in many pockets, and the power-draining backlight of the LCD screen (which cannot be turned off) meant Game Gears were unusable after a short period of time. An AC adaptor can be plugged into the system so that it runs off the mains, but this was not considered practical for consumers of the day.

Game Gears were also manufactured at a time where capacitor problems were rampant across the electronics industry. As a result, screen and audio failures are common, and fixes are not always simple.
