Ok, so far it's about the same. All renders are by Aleksey90 the dev. of this game. there are differences but not much. There is know way of knowing how long it will take to match up to original BB, it's just getting started. If I had to guess, I would say 2 years, but it's really hard to say at this point.
Here's a note from the dev.
Hello! I am Aleksey, and I have a huge passion for creating high quality 3D Artwork.
The purpose of this Patreon is to provide a platform for me to resurrect the abruptly cancelled adult game - Big Brother.
The direction I go with the project all depends on how deeply I immerse myself with this work.
If the page attracts enough support for me to turn this into something more than a hobby, I'll have more resources at my disposal to add plenty of interesting things, including animation, which is so lacking in the original game.
