You forgot Shining Force cd for stretegy/RPGs and Popful Mail and Dungeon Explorer for action/RPGs. Their also is a Dungeons and Dragons game but I've never played it. Eye of the Beholder if I remember right.
Also if you include import titles these are also RPGs.
the working designs rpgs more than make up for any lack of quantity. my buddy sean swears by dark wizard. i guess that's more of a stategy game. i swear by ecco the dolphin, that's not an rpg at all, but it's got great music
