As ProjectH has a rather impressive sex sim in place and they have kept their word so far, I do not have reason to trust that they do not know what they are doing. Their budget keeps growing month by month. It should be safe to say that they are on track.
Similarly, I do not have reason to trust that they do know what they're doing when it comes to gameplay. We've seen literally nothing of it. And a large budget does not automatically mean that the product will be good. So, for my own safety, I'll assume the gameplay will be mediocre at best. If it's good, then I'll be pleasantly surprised. If it's bad, then I won't bee too disappointed.
Ubisoft devs are working on this? Oh boy, cant wait to climb towers and search collectibles in a generic open world.
Apart from the fact that they're said to be Ubisoft employees, we don't know what their job description was/is at Ubisoft. So I'm again going to be cautious with this and not assume anything. Saying you work at a AAA studio does not give me a good enough idea of what your competency is like. And it also doesn't mean those skills will translate one-to-one to working on an indie porn game.
I was hoping that the main gameplay would be somewhat lewd.
We don't know that it won't. At least I don't remember statements proving or disproving that idea. I'm at least hoping the sexual content is at least somewhat connected to the gameplay and not totally separate. I think I remember reading that how well you do in the missions affects the girls' mood in the lewd content. I don't know if there's more to it than that.
