There should be a storage building for starships and/or relics/instructions/other ancient things/compounds.
Here is what I made:
A place for you to store your starships before they are needed
Stores: 10,000,000 starships
tile size: 8 * 8 (64)
requires workers with 120+ iq, blue collar
employs 1,000 workers
produces 1,000,000 money/minute
uses: 100 triantanium, 10 civics and 100 robots to keep running
Tell me what you think!
