I just made a wiki on wikia novelas, called Forsaken Earth. This project is about open universe project, which you can contribute, develop, use in any way you like, aimed for the story frame for games, short movies or whatever you want.
This one have been in my head for some years, then I found wiki, so I decided to post it on wiki thought might be useful for the community.
The universe itself is all about combination of mythical creatures combined with future, in a very dark theme.
If you’re interested, go and check it out at :

Strangely, I had a similar idea in my head for some time.
Create and develop a world with visual aid from Blender free for all to use complete with all a world needs… But I abandoned it because it’s too time intense.
It seems interesting 
If you want to, I have some resources which may aid you.
