Recommendation of the day: Lufia - The Legend Returns for the Game Boy Color. One of the most gorgeous GBC games and an RPG that's way more robust and clever than anything I've seen on the system. There's a lot of little neat tricks and the main party gimmick encourages customization.
Also it lets you defeat "unwinnable bosses" and tackle parts of the game you're not meant to yet.
