This projects feels to be too much for me, I am not sure if I will ever keep on working on this, because there seems to be no interest. It is a huge amount of work to do, until I would be happy with it in UnrealEngine5. I think I cannot do all that alone in a reasonable time, as I do this only as a hobby beside my full time job to keep going.

It was a funny ride so far, but for now the project is on ice and Im trying other things.
