I was thinking about other mid-game / late-game industries that could emerge, with the added robustness of multi-step contracts.
What if there was a “Base Repair Service” contract, where players could bring the necessary materials to a planet and essentially perform the “BRA” command on other player buildings, for a fee?
For prefab manufacturers, it could be an interesting new industry that I - for one - would happily pay a hefty premium for. It would also add major emphasis on the need for additional ships (especially high-capacity ships), and thus more emphasis on fuel consumption too, to send ships out to customer bases to provision the repair materials.
Just an idea!
