It’s worth looking into Lutris for non-Steam games as well. Comes preinstalled with Bazzite (heavily gaming-optimized Linux distro), though I don’t have any non-Steam games to try it on since Steam works fine for all the games I play.

I really don’t like it. That’s a term that I’ve only ever seen associated with porn and sexualization, and I’d prefer not to be sexualized or objectified. I agree with you that I find it dehumanizing, and I really don’t like being fetishized. I feel like anyone that would use that term for me is either a chaser or a transphobe, and I don’t want to interact with either. And that’s without getting into the whole Japanese culture talk, which revolves around traditionalism, heteronormalcy, and misogyny that makes it extra uncomfortable.
