Back when this was only known as "Final Fantasy Legend 2" and I still actually played Final Fantasy games, I rented the game from a Mom and Pop game rental store that rented out GB games. Almost instantly I was in love with the strange game that played nothing like the other games that shared it's name. No Exp? Weapons that had to be taken care of or they would break? An RPG that was actually difficult? I was amazed and stupefied by the game, and it arguably is the game that really got me truly and utterly hooked on off-beat JRPG's.
Years later, I actually bought my own copy from a Gamestop, and to this day I consider it one of my favorite GB games of all time.
