Correct me if I’m wrong, but wasn’t there an indie game company with a majority of their designers being part of the LGBTQ + community? I seem to remember something like that.
I was recently reminded of the fact that Green Ronin seems to employ a number of LGBTQ+ designers. Which honestly shouldn't surprise given their level of support for LGBTQ representation with things like Blue Rose. No idea if it's a majority of designers though.
