A suggestion regarding height.

[Risvertasashi]

What this game already does is have somewhat equal hight between genders (if you go with F 100 and M 0)

I think that's the very issue. OP & others would like the ranges to overlap, not "maximum value for females ends where the minimum for men begins".

Secondly, technical issues do block feature development. So yes, it's worth discussing (IMO anyways). If a dev swoops in to say "we can't do this for technical reasons" or even "actually we could do this pretty easily with our engine", it's not like no one will believe them.

I disagree; in fact, I was surprised at how natural it looked, compared to what I expected.

I can think of 99 words to describe that upscaled Au Ra F and "natural" ain't one.
