I admittedly know next to nothing about the development of these games. Therefore the question: is continuing with this - by all accounts - outdated engine not risky? Can the game reach the finish line before grinding to a halt due to obsolete technology? Would it then not be better to have a clean break at the start of Chapter 3 and move over to a more current and easier to use framework?
Hmm, I think....
If the game developer had to familiarize himself with another program that was certainly still completely unknown to him, the only result would probably be that the next updates would be unnecessarily delayed by an additional 3 to 4 months.
Sure, the whole game would be perfectly pretty nice perhaps allthough build on DAZ 3d.
But tens of thousands of graphics and animations would have to be completely reworked and may be hundreds of thousands of script lines would have to be rewritten too.
You are welcome to produce this remake of the game yourself and do the work all by yourself like Altos_and_Herdone did in the early years of this game.
Besides, I wouldn't want to change the graphics from next chapter on, for many of the characters I've seen grown up fond of in the game.
So talk to Altos on his discord. It is best to discuss your change requests with him in detail.
Oh yes, you could of course achieve the greatest success if you became the highest paying patron for the game. Join as the main Patron! And all your wishes come true.
