Hmm, more of a strategy game, but Advance Wars: Dual Strike is lots of fun.
Also, right now I'm playing Golden Sun (and the sequel) from the GBA. Considered one of the best RPGs from what I hear on this website. I've had lots of fun with them.
Other than that
Fire Emblem: Shadow Dragon - SRPG, and probably one of the tougher ones you'll find. Also one of the best strategy series out there
Chrono Trigger - Great RPG game. I'm sure the remake is at least as good as the original
