>>1 OP I do think it's a nice idea in concept, but is it really no, unless you are going to keep talking about LGBT issues while playing games?, there are a good number of mature gamers who don't care what you get up to in your personal life at home, it's not like anyone is forcing you or anyone to reveal that kind of thing while in a chat group, that is up to you alone.
you also have to realize that some guys do RP and play as female characters or even have their male characters dress effeminately and will RP them that way too.
I have seen someone try an make at LGBT guild a in a few online games, but is there really any point to that as long as you and your friends and other people in the same game/guild/clan/ and are having fun that's enough right?
