Don't know if anyone mentioned this to the Dev, or even if the Dev recieves notifications from this thread anymore... but it's Renpy right? Instead of thinking he needs to do the same scene 9000+ times for each of the possible combinations, why didn't he do layering?
The Fixer for each scene instead of doing one for every variation in the game, it's one scene but skin tone, eyes, hair, bust, areolae, outfit, outfit coloration, jewelry, makeup, bodily fluids etc are all layered... it may be hundreds of combinations, but regardless which combination the player picks, the Dev only has to do the art for each piece once. In fact, iirc, Sam_Tail is trying to get it to work for custom colors as well. It's done so well that you'd think each scene is individually crafted, instead of a composite made with many pieces coming together and working in unison like a band, or symphony. Doing it this way allows Sam_Tail to work on things without being bogged down doing the art for each scene for months at a time. The only exception to this is an optional story line mission, but you can go back to full custom after.
Even if this info doesn't renew interest in the Dev to continue this project, maybe it'll help someone else who considered making a game, but the thought of having to do each scene for every possible combination available seems too daunting or overwhelming. So, dear potenial game/VN Dev reading my post, RenPy allows layering. Though nude, shirt1, and shirt2 will require 3 art works, you'll only need to do the body once. When you do shorts1, you only will need to do one art work, instead of doing the scene 3 times. Again, when you do miniskirt1 you'll only need to do one more artwork instead of having to do the entire scene 3 times (nude, with shirt1, with shirt2). This will allow you to increase the level of complexity of each scene while only adding a minimal amount of work per new addition instead of an exponential workload. So if you wanted to do a scene in a different position, you'll only need to do 5 art pieces instead of 9 entire scenes. Not only will this save on workload, but also upload/download size as well.
I know people don't like the Darks Arts practiced on forum threads, but it needed to be said.
