No, I wish I had saved the file, but I had won the game (by time.....sheesh) and deleted the files. I agree, if I was out of Aluminum, I would still expect to see the Spaceship Factory, but grayed out.
Anyway, I guess I'm thinking that Science Victory can be tough, as opponents know that the Apollo program is underway and surely someone is chasing a Domination Victory and planes/nukes/etc will show up within a few turns. Trying to stay strong for the eventual challenge sucks up happiness & gold. Such a delicate balance, that it is so easy to just decide to go for the Domination Victory, as you would have already built up significant forces.
I've been able to get Domination and Diplomatic Victories easily. Science is tough and Cultural is confusing (hard to understand if you are winning or what it takes to make progress.....staying small makes you an easy target and there is constant war).
Just a beginners thoughts.
