Well, the gay men I know tend to play all sorts of games, as they tend to watch all sorts of movies, which makes them compatible to us 'others, but foremost it makes them compatible to each other, which explains why they usually come in two, as couples.
All of them have met through work or some cultural event, at least that's how their stories go.
Most 'other', non-gaming gays I've met are more focused on carnal pleasures, saunas, easterf**k, with more of a hive-mind approach to virtually everything. Also, it's these folks that display a decidedly anything goes attitude, which makes them compatible to like-minded gays, but seemingly only for brief moments of interaction involving lots of friction, both of the loins as well as of the social kind. It's this group that is very, very vocal, and it's members of this group that tend to denigrate and pester members of the first mentioned group, as they seem to consider themselves spokespeople of what gays have to like and dislike. They are generally obnoxious and annoying, and they consider games stupid and non-essential, yet still celebrate any and all gay content in any available media. They all know about ME3, and they all love it, even though the large majority of them have never actually played it.
We find it easier to interact with members of the first group, as their lives are pretty adult, normal and interesting, and don't revolve exclusively around humping and drama 24/7. Also, they don't like ME3, which makes us brothers and sisters in enlightenment.
One couple has met on a, well, leathery bondage sort of event because we brought one of them with us. The bondage equivalent of a group hug ensued together with hilarity and a good time for everyone involved, the guys hooked up and have been a couple for over a decade now, with them sticking together through good and bad.
Don't give up, hang in there. Enjoy yourself and take good care of yourself. Be open and alert. Don't expect people to click with you just because you share one specific preference with them. It doesn't work like that for men, women, kids, Christians, Muslims, gamers, smokers, cooks or dog owners, so I think it's really not that tragic.
