Games to play with your girlfriend (I don't have one yet)

A comprehensive list of games perfect for playing with your girlfriend. It’s a work in progress, and honestly, the only reason it’s not finished yet is that I don't have a girlfriend to test these with. Consider this a collection for those of you who are actually lucky enough to have a player two! Feel free to suggest more titles in the comments—I'm keeping this list growing even if I'm currently playing solo.
