What kind of games are y'all playing? In the games I usually play the sexual orientation of the characters isn't mentioned at all. So for all I know they could be straight, gay, bi, pan or whatever.

The last game I remember playing where the protagonists wife was mentioned (implying he's not gay) was Max Payne, 25 years ago.

The engineer in Factorio doesn't care for men or women, all he cares for is that the factory must grow. And afaik it's never mentioned wether Jebediah Kerman is into Bob, Bill or Valentina. None of the thousands of enemy soldiers I have shot in various shooters ever told me whom they're in love with. And all the Sims I might have killed by burning down the city were just numbers for all I know.
