That is a tough call. If she is not a gamer because she has never had a chance to play video games before, the SNES is certainly a good system to start with, as it has a host of excellent titles from various genres. FFVI would be next up, if she is continuing with RPGs, then Secret of Mana, to switch up the combat a bit. Super Metroid is an awesome sidescroller. It's just important to look first for games that you think suit her best.
