transguy here. I've not seen that kink anywhere personally. I mean, the same can be said for cis guys who fetishize trans women, some will use derogatory terms which I won't name here, but with any trans person, there is going to be those that fetishize, misgender, or otherwise are disrespectful. If this game adds FTM/transmasculien characters, I'd hope they would be portrayed respectfully. same with MTF/transfeminine.
