All of those cool systems like black holes, nebulas, organic infestations, ect. need something to make them a benefit provided the right technology is researched.

Take for example the Chigs from "Space Above and Beyond". They were abable to exploit black holes and gain a strategic advantage and move about them freely. Or perhaps if pollution is factored into SEV, wouldn't this be a great dumping ground for all of that pollution. Or agian a place where limitless sources of energy are aquired.

Organic Infestations could be a boon for those oraganic trait races. Birthplace for organically grown ships? Any planets in this system would have an added shipyard rate for organic races.

All of these could have a seperate technology tree to expand the tech tree more and add more play style options.
