Game Gear games were to come in the form of interchangeable cartridges. Like the Gameboy, these come came in plastic cases for storage which was a nice touch. As a pack-in game, Sega included Columns, hoping to latch onto the Tetris craze that was introduced with the Gameboy. Â
Even though the Game Gear is more or less a portable Master System, the games cannot be directly played on the system unless using the Master Gear Converter, an add-on released by Sega to enable Master System carts to be played on the Game Gear. Master System games play remarkably well on the small handheld, making some games such as Sonic 2 easier due to the higher screen resolution of the home console.
