For the most part, the 3D models are and renders are incredible. I've seen the same assets used elsewhere, but the quality just isn't as high somehow, and they usually tweak the body proportions to make things bigger, which just makes me lose interest.Especially Last of Us
Back on topic, the reason why this game is popular despite being abandoned is that it probably has the best 3D models conpared to other games.
The mom in particular is 10/10, with the right and realistic breast size, and incredibly attractive face. Even though this game is really just pictures (compared to others that have animations), it's still a delight to see the cgs.
I don't really miss the lack of animations. I've seen them in other games, and they can be done well, but more often than not they're just clumsy and not particularly sexy. Big Brother could use much more renders during sex scenes, and a little more explicitness with regards to female genitalia, penetration, etc. Or if we could have animation like what TCMS put in his versions of the games, I think I would like that.
