It came out in beta form in one of the patches so it's incomplete and probably released to satisfied the complaints of not having one, comparing to 3DCG.
So we should talk about what many people cared about, the pose system. Basically all I'm saying is that if you're expecting Artificial Girl interactive level, you'll be disappointed. Basically, they feel like rag dolls since rather than NPC's, which is sad, I like that red head nurse or the headphones girl. I know that's minor in comparison to how small the interactivity you can do. I know this is usually to attract a wider audience but the main girls personality is bland and unlike other 3D sandbox game of it's kind, the NPC is stuck in one place as in if you try and carry them anywhere aside from that area they despawn, so they can stay in one area. You can toggle which clothes they wear, carry them around the area and of course, virtual sex.
I like is that they all have a unique voice and thus they have a certain charm that I like with some of them. They range from office girls, beach girl, nurses, school girls, maids and a lot other types you know and love. Some are hidden in the smallest of places and some are blatant obvious to find.
Well you're in luck, there are 23 NPC's in this game. So the next part you'll ask is the Non-Playable Characters. Why yes, a wooden torture table is quite comfy.
