Now that you mention it, there is a lot indeed. ._. Kid Icarus Uprising which I heard was really good, and then KH3D which speaks for itself. No FF yet apart from the rhythm game, which isn't really a must-have. Still there's a lot! I think they also have a Tales of the Abyss port and a certain Fire Emblem Awakening, but those are a bit obscure (I'm one of the few people would want those in my hypothetical 3DS so bad, haha). And then there's Ace Attorney 5, Professor Layton vs Ace Attorney, two Professor Layton games I think, Luigi's Mansion 3DS, Ocarina of Time 3DS, and the list goes on. Anyone well versed with the old DS library would consider the 3DS library a haven. ;D
