Great concept! I'm using another ruins mod too.

In fact, I think it would be interesting to alter the current research system and require ruins to be scanned to unlock research topics. Once researched, they can be obviously be built, but also collected from ruins with a 100% success rate. It would promote exploration a lot.

That said, I would love if this was made compatible with Resource Spawner Overhaul.

He must add to exception all prototypes that he doesn't defined. I've asked this, but he don't want it.
Another solution: write huge, write really huge table of all entity prototypes and add it to the RSO's library. This table will be bigger than all previous tables together.

I don't know how to make it compatible.
