At this point in development, it's pretty much unfeasible to add a race system. There's plans for body shapes, but likely not to that extent as that requires way too much graphics work for the varying clothing sizes.
Atleast make that if you are from a race that an npc is that npc has something interesting to say, like, if you are catboy/girl/person gin and cassie aknowledge you as an equal making their quest lines easier and shortier
It's probably something with having to redo everything from the beginning of the systems and having to tweak so much. Indivi got a bit of works to do with art, program and fixing bugs already.
