Well... I'm somewhere in between. I'm a straight male, and though I will not base a decision to date someone on whether they are a gamer or not, I would definitely need my wife to play, or at least appreciate the artistic storytelling aspects of games (but preferably play). It's not just some shallow desire to play video games with my wife, but interactive storytelling is my passion, it's what I want to do in life. I need someone who understands that, and shares that interest.
My current girlfriend is not a gamer, but she is really interested in learning about it. I've gotten her started on a few games to try and figure out where would be easiest to start (she is really new at this: she has trouble grasping the controls of pretty much any game I give her). Basically, I have a clean slate to teach about video games. Someone who understands art and storytelling is asking me to introduce her to the amazing world of interactive fiction. And it's awesome.
