So I think a cool addition to the game, especially with trade cities becoming a thing and thus more travel to playermade cities, would be a commercial ship factory.
It would be exactly the same as a regular ship factory except it would also function similarly to a chest shop.
The blueprint owner would set one up and set a profit price. The customer would activate the factory, as normal. But they would pay the cost of the ship plus the profit price the owner set.
Maybe make it check if the customer has all available credits so there is no half built ships from poor folks lol.
