I wonder if Dorian is the first playable gay (male) character... of all time?
Because that would be awesome!
I really had to rack my brain to think about this one. It was harder than I thought. A lot of the LGBT characters are 'hidden' with ambiguity, but there are a few that are pretty obvious:
* Arcade was an NPC follower in Fallout New Vegas, but while he plays a similar role to Dorian, he wasn't able to be switched to in combat.
* Jacob Ritter in State of Decay is gay, but through random event generation, he might be bisexual if a 'romance trouble' event generates between him and a female character. In the scripted story, though, he's presented as gay (although I guess he could be bisexual since it's never stated that he's not)
* There was a playable gay party member in one of the Persona games (although I'm not sure which one)
* There's a slightly ambiguous but still pretty obvious gay squad member in Valkyria Chronicles
* Big Gay Al was playable in the South Park racing game (What? He counts!
But honestly, that might be it. Literally, those might be the only examples of scripted gay men who you can play as in video game history. How sad.....
