Fun Mod Concept

[Kamog]

How can we stop Waldo from building more ships? The dreadnought will need a space yard on it so that it could construct fighters, mines and drones. The race will have to possess the technology they needed to build their super dreadnought, so wouldn't they be able to build another one just like it?

...oh, maybe their only dreadnought will use up exactly the amount of resources the race will get each turn to maintain it, so they couldn't pay maintenance on the second one. But then they won't be able to build units, either because they'll never have any resources left.

Is there some way to mod a space yard component that only constructs units?
