Hello, I'm trans non-binary and I'm genuinely confused on what you find wrong about trans characters in this game. Refering to another one of your responses here, we don't always wear pride flags, it's not really a bother that there are so few items with them in the game. At least they're there and easily accessible! And what do you mean exactly by "shouldn't I at least be able to express my characters gender other then thigh-high socks"? Because you absolutely can, you have the freedom to wear whatever you want in this game without any gender norms pressure. Feels pretty trans friendly to me! And all the things you mention about the "suffering of the trans community", is it implying that you think there should be transphobia in this game? My life is enough of a nightmare just because of my trans identity, being able to be fully accepted as a regular human being in a game feels so good! Because we are regular people, so I don't really see how and why this game should treat us differently than cis characters.
HRT system isn't that bad of an idea, especially for mid-game transition, but the game is still in development, so it might not be a priority for now. Still could be cool tho! As for trans visibility day, I genuinely don't know. It seems like every holidays in this game is strict to its lore and comes with a special event, so I don't really know how that could be implemented. And it doesn't matter that much to me honestly, again, just the fact that we are treated like normal human beings is more than enough for me.
Even tho your wording feels a bit off sometimes, I can understand that maybe you mean that "a trans life will have unique details about it that a cis life won't have". Which is true honestly. But the game is still in development after all, so it's normal that it lacks some gender identity specific details. As long as I can play as my transition goal, be openly non-binary and never be discriminated against for it, that's all that matters to me at this moment.
