Sega is a provider of various entertainment products including digital contents, home video games, amusement machines, animation products, toys, and more. The SEGA Game Gear was Sega's answer to the NINTENDO Gameboy, and it was the best selling handheld ever sold that was not made by Nintendo. While there were many different Game Gear Packages offered with various carrying bags or pack-in games, the only significantly different version to speak of was a Sports version, and a couple others that were different only in color.
