Now that games have started including non-heterosexual characters is it so fucking hard to include at least one closeted LGBT character? Just one?
Obvious question: how do you know they haven't?
Unless you subtly reveal or imply the character's sexuality, it's not actually in the story. It's simply unknown.
And no, you don't need to have "that conversation" just because you include a gay character in your story, especially when having that conversation makes no sense in the time period and/or setting.
For instance, suppose you're making a dark fantasy RPG, and you want to include a gay character. Maybe instead of expressing this through blunt, simplistic dialog, you can have a scene where your party comes across some guards yanking two women along in shackles, and when you ask the guards what these women did wrong, they tell you the pair are to be burned at the stake for having homosexual relations. At this point you can include a quick cut-away shot of that one member of your party (who was earlier implied to have lost a loved one, and who never seems to show any interest in the opposite sex) staring blankly off into nowhere like someone just shot his dog. Oh my god it's almost like you said something notable about a character without hammering shitty dialog into the player's skull
But maybe this would make gay people upset, or something? I dunno? I guess no one wants anything bad happen to non-orc, non-chaotic evil characters in a fantasy story?
