The full-color portable video game system that separates the men from the boys.
Needless to say, it didn't do quite so well when compared to its competitor.
Not that it was a flop, mind you — it lasted from 1990–97 and sold 10 million units. That might not be as impressive as the Game Boy's 118 million, but it was the most successful handheld to go against Nintendo until the PSP, and had the advantage of being in color at a time when the Game Boy was still in its green-and-black days.
However, the biggest issue was battery life. Even if the chips didn't consume a lot of power, the mandatory backlight (as in you couldn't turn it off) did. It took six AA batteries, and even then only lasted 2–5 hours. Another problem was the first runs were faulty, and that along with the battery life caused the audience in Japan to largely ignore it. This led to only minor support from third parties.
Even then, it's not a system to ignore if you have the batteries or an umbilical AC adapter (conveniently, it was compatible with Sega Genesis AC adapters).
In 2001, third party game developer Majesco, with assistance from Sega, reissued the Game Gear for a reduced price. Only a few games were re-issued with it (notably Sonic the Hedgehog Chaos and Columns), it still had the battery problems and aside from the retro gaming market, did not catch on with the consumers. It was gone again by the end of the year.
Aside from the display, these specs are nearly identical to the Master System. This allowed many games from the Game Gear to be ported to the Master System and vice versa. There was even an adapter, called the Master Gear, that allowed Master System games to be played on the Game Gear. A hard-to-find accessory called the TV Tuner was made available at one point, which turned it into a little television set.
