Of the women I've dated, only one was ever seriously into gaming. This was in college, when we were in the same dorm and often went to the other's room to play games. It was certainly a blast to play through Ocarina of Time together, while making jokes about the game. We'd also play Starcraft, and play through old NES games like Castlevania. Still, I'd say gaming was only a small part of the relationship; there were so many other amazing things about her. Maybe or maybe not it was a coincidence that she was also the woman I was most fond of (we'd have continued dating had she not moved to another country).
Anyone else I've dated actually flat-out disliked gaming, as they weren't into any activity that kept them cooped up in the house/apartment. This wasn't a problem for me, though, since it encouraged me to get out of the apartment more! In fact, getting older, I've found I've had to be somewhat discreet about my interest in gaming (not bringing Zelda up on a first date, not having a giant collection on center display in my living room), since it's easy for a girl to then perceive me an antisocial loser before she's gotten a chance to know me.
^it would be a problem for me if i felt like i had to continually downplay my nerdiness in a relationship, but i definitely understand wanting to keep that somewhat hidden early on before you really know what kind of frame of reference they have.
before i tl;dr anymore:
“Being a geek is all about being honest about what you enjoy and not being afraid to demonstrate that affection. It means never having to play it cool about how much you like something. It’s basically a license to proudly emote on a somewhat childish level rather than behave like a supposed adult. Being a geek is extremely liberating.
I was reluctant to tell my girlfriend that i was on a raid team in WoW before I knew she had a gaming history, but part of that reluctance was that I knew she had a douchebag ex boyfriend that would ditch her for his guild activities so WoW sort of involved some previous bad experiences. I also got the impression at one point that she thought playing pokemon at our age was a bit childish, but I immediately told her how recently i had played those games (within the past three years) and a month later i actually got sucked back into the pokemon franchise and now we actually play pokemon snap together and she is making a pair of eevees out of clay art with some personalized touches that represents the two of us. (yes, we are a bit schmoopy)
