Not a game, but a feature I wish the 3DS had: Built in Rumble. Perhaps the 3DS would have to be slightly larger to accomodate for it, but given that DS games could rumble with a cart the side of a GBA game, surely such a feature wouldn't have taken up too much space inside of the 3DS. Not the biggest of deals, but it was a nice feature that I always wished the 3DS had built into it, or at the very least some sort of adapter that connects to the 3DS and communicates via the infrared port to give forced feedback for compatible games.
