Sega Game Gear
The Game Gear was Sega’s entry into the 8-bit portable gaming market. Hitting the market in 1999, just a year after the Game Boy, it distinguished itself with a 32-color display and horizontal orientation. The Game Gear also introduced novel peripherals like a TV tuner and screen magnifier. Despite these improvements, it was overshadowed by its predecessor; the Game Boy sold 10 times more units worldwide. This was most likely due to the Game Gear's game library, which was limited compared to the Game Boy's, as well as its relatively late arrival on the handheld scene.
