Aloy is a VERY complicated figure to mass produce, her outfit is so rich with details and stiching that it would take a long time to mass produce each individual tunic, her hair presents another challenge tho with proper R&D I think one could create the hair in sculpted format, that's probably why none have made her yet.
I should've explained the "no one caring about accuracy" part a bit better, most collectors care but are also impatient, especially with third party figures, as long as the figures looks like source material it's fine to them, they don't need it to be anything more, we on the other hand are obssessed with detail and would take our sweet time developing the armor and all it's minor details, it would take time to develop and produce and by then VTS would have already released their figure, rendering our focus on accuracy completely worthless as collectors would already have a figure they're satisfied with and would not buy another one just because some things are more accurate, hope it clears that up.
