This mod is awesome!
Heat mechanics, as far as I can tell, are underused and this mod really draws attention to the strengths and weaknesses of nuclear power, which doesn't scale it's usage like the easier steam engine and instead burns a fuel for 200 seconds.
Is it possible to build a circuit that can turn off the reactor and shunt away heat in an emergency? Again, this is another way of highlighting the logic and circuit tech, which I have neglected to use even after 250 hours of gameplay.
My point is, you can "beat" Factorio without using circuits, understanding heat mechanics, or avoiding a nuclear emergency. This mod really stretches out those game play mechanics.
