I had to check. They actually said this. I’ve never played Warhammer (I have been interested, just haven’t gotten around to it) and I don’t know these devs at all, but contradicting themselves with just seven words in the same sentence is actually kind of impressive.

I see your point about distinguishing between fuel types. I typically take fossil fuels as meaning non-renewable, carbon-based fuels though. Wouldn’t uranium and other nuclear materials just be non-renewable fuels?
