Okay, I am running into a little problem here in a game. To the point that I really don't even care about some of these planets now. I am really late in a game. I had a huge map with all races. It is down to about 4 of us now. Well, here is the problem. Occasionally I will be outnumbered in an invasion, so I will use Tidal something(can't remember the exact name) and that of course destroys a lot of the buildings. Well, If I try to build anything on the planet back up, then it will take like 500 weeks! I try to start out with an advanced Factory, in hopes that that will help speed up the build of the rest of the planet.
Any advice on building from scratch late in a game? Is it possible to build the basic manufacturing plants first? Any ideas are appreciated.
