Well, if she likes the SNES, you may be able to get her into PC gaming with Terraria or Minecraft... Terraria especially feels like a throwback to the early consoles... plus both are pretty easy to set up for multiplayer so you can count it as "quality time"
I can't offer much more than that though... my gf of the last 10+ years plays L4D, Civ, Fallout, Red Dead Redemption... she's a real gamer already hehe
