Black Holes and Temporary Sub-Space

[Mr. Mortius]

It might be interesting if every month or so, all the new black holes would open up wormholes to a small area of sub-space, maybe a few sectors in size. Inside this sub-region are exotic materials, and controlling a majority of the space grants empire-wide bonuses to the empire holding the most territory. After a week or two, the region collapses in on itself and all cities inside are lost. Any cities and ships inside are destroyed, and avatars teleported back to the main galaxy.

Sounds fun, though I slightly prefer the battlezone idea, given it would start with an even playing field each time. With this idea, the most powerful empires, who also have the most resources and knowledge of many black holes, could swamp the subspace area from all sides.
