What are facts about the Nintendo Game Boy?

The system was originally released in 1989. It featured a gray-scale screen, two game play buttons and a D-pad for directional movements. Games were played using a miniature cartridge and the Game Boy was powered by 4 AA batteries. While the Game Boy was great on the go, it often ate through batteries fast, especially since it took 4 batteries to operate. The system was fragile as well. If the screen was hit in any way, it could easily crack and prevent the Game Boy from functioning again.
