Game Rec? Something Wife and I can play together?

I'm looking for a game for the wife and I to play this winter.

Me: FPS has been my fav for years. But also like adventure/puzzle types.

Her: Hasn't really gamed since Mario Cart on SNES. I built a RetroPi and she loves the older games. I've never heard her unleash a string of obscenities like when she got back into Super Mario.

I'm looking for something we can play co-op, and also head to head once in a while.

Thanks
