I put together a list of games for every letter of the alphabet with playable female characters that I've personally played and a lot of them are pretty old.
Yeah, I think "Transfem" would be a more accurate and just overall better name. I agree it's better to focus on where we are rather than where we were. I never liked MtF because in my view I was never "male". Transfem just describes what I am and always have been.
