Playing though it, it feels to me like he wanted to make money, so he bought a bunch of things from the Unreal market and threw them together. When you really look at it a lot of things just have a different style. Maybe I am wrong, but to me it seems like it's just a cash grab and not something that will be quality. I say this because of how the game actually plays and how the animations have such bad clipping.
Take the NPCs for example, almost none of them match. The beasts somewhat match, but then again it's not hard to match fur. I know you can buy a lot of nude things on the marketplace, so to me it feels cheaply thrown together. Again, I could be wrong, but I am pretty sure this it the case.
