Ok, here is a map that I have had lots of fun games on.  Best done with a rock, no atmosphere race.  It is a small spiral with no warp connect.  Its from way back in Version 1.11 and has a few planets next to black holes and within nebula.  Great fun with max races (havn't tried multi.).  I heard that someone is making a map with sphere/ring worlds on it, anyone have a copy??  would love to play where you can find and colonize one, or find the AI with one in it's grasp.
