its something phenomenally easy to test out.
Set the cruisers and cruisers base energy output to +999999 or something ridiculous.
its a hamfisted approach to making an example of a "no energy economy" but it would work for an example.
Not sure what you mean.
So I'll take this moment to expound on my view of energy use for the nkg. If I remember to build them before my first cruiser most of time I don't for some reason. Anyway I usually build a small block of them at the start and declare that my base. That is to say it gives some reason to hold ground. Though it still feels like an after thought.
