The chances are too high that the proportions are too big for my tastes and there is no way to go around it except using the Creator Build. I don't mind big breasts and/or asses, but some people like them way bigger.
I feel the same. But I've played around with the creators build and decreasing breast size results in rather weird looking breasts pretty quickly. The creator probably likes them big and likely doesn't care about other peoples tastes. Similar to the issue with hominal and feral males.
What worries me more is that in a breeding game, the creator keeps working on adding new content and animations even though the breeding system is not functional.
Yes, I know you can breed the monsters and get new offspring. But the core principle of breeding different traits requires the offspring to inherit the parents traits to some extent. Currently it just presents you with a new nephelym based on presets.
The whole preset thing is a step into the wrong direction. With a system that generates the appearance based on parameters, appearances for wild nephelym should be determined by random values using gaussian distribution. And Offspring should be based on the parents values with possibly some small mutations.
TLDR:
Core game play is missing
⇒ hardly anything to do.
Creator adding more assets.
