Remember? Heck, I still play SE3 once in a while. I even played SE2 a few months back
I remember some mod that gave an "Enhanced Spaceport" technology, which was supposed to give you a spaceyard. I also remember it didn't work when I tried it
I also remember the reduced facility build time, going in increments of 2B (IE, 1M = 10 turns, 2000M = 5 turns, 4000M = 3 turns, 6000M = 2 turns). Although I'm not sure about sending in the transports with colonizers as my favorite racial advantage was Natural Merchants
Resupply Depots could wait, since ships had 1.5 turns of supplies instead of 50 sectors minus weapons fired. Ah, the good old days of not worrying about supplies so much...
