[quote name='corrosivefrost']Too many buttons for her in SSF4 -- 3 punches, 3 kicks, special move motions? Trust me, not for her.
She likes most of you list -- We started NSMB Wii at one point, but started getting irritated with each other on some of the more challenging levels. I'd rather play anything on 360 or ps3 over Wii though -- that system just pisses me off on so many levels. It's got a few okay things, but I just don't like much about any of it -- controllers, games, etc.[/QUOTE]
I'm not your typical girl in the sense that I tend to like the same games most guys do, but I do have some suggestions for you:
-Katamari Forever
-Castle Crashers
-Critter Crunch
-ModNation Racers
-Eternal Sonata/Tales of Vesperia (has 2-3 player co-op)
Also, have you considered getting her a game that only she can play? I know you said you wanted something both of you could play, but maybe if you introduced her to a game with a heavy single player experience, she will enjoy games more. Perhaps something like Heavenly Sword or Folklore, a game with a main female protagonist?
