Custom map, I ruined a spiral galaxy design and kept punching it until it looked not normal enough to be interesting. You start with 1 star, lvl 16 Hyperspace and lvl 2 Scanning. Terraforming research is deactivated. 66% victory.
1 starting star was not ideal but any higher and my map would always award more starting stars to 1 or 2 players while the rest got the set number.
Premium only, dark start.
