Wow this is really cool that she's playing Turbo with you. Maybe my old lady will do the same one day.
So far the only 2 games(since we've been together) that my wife has spent any decent amount of time with is Animal Crossing: New Leaf and Disney Magical World on 3DS. Amazingly enough, she put over 100 hours in AC and over 300 in Disney. The only classic era game she's played with me is TMNT IV on SNES. She played about 10 minutes and said she enjoyed it, but then went to do laundry. I guess that's a good problem though haha.
