WhiteRaven literally hired someone to speed things up, according to the goals there should be another 3d artist hired but I guess that never happened. Pretty sure every update after the hire only took longer and longer with less content then before surprisingly. Every new release still needs 2 to 3 bugfixes at the very least to actual be able to play the new content.it takes as long as it takes. Too many projects on my mind that were closed cuz of the pressure of the their own fan-community.
The people that have worked with DAZ studio will know that once you know how it works it only takes a very short amount of time to create new content. To tell you the truth: the entire set of bimbo-scene variations could be done in 3 to 4 hours and yes, that does include rendering (if the previous scenes were saved obviously). So there just aren't any excuses at this point to explain why it's such a snoozefest.
With a montly income of 2.8k just from Patreon, I for one do expect certain standards. Although I do enjoy this game WHEN it works, I do believe this project is one of those that should be closed.
