I know she didn't like the wii that much but if neither of you have tried too many RPG games the Tales of Symphonia series (there are 2 games) of which the first one is the better and you can play co-op (battles, only one runs around but you can solve the puzzles together). I've played the first one 3 times, once alone, once with 1+ friend and once 4 player co-op which was great fun ^^.
