When I was young, I got a GB color and a copy of Crystal. I could of chosen any of the games, but I wanted Crystal. I kept it with me for a LONG time. I recently loaded it up to see if I could finally catch Entei and then Ho-oh. Well....my save was lost. The battery in the cartridge finally died. It was a fun ride and will still remain my favorite pokemon game. I still have the cartridge, along with my later acquired yellow and blue. Thankfully my yellow still works
