Currently playing the Star Trek total conversion mod (which is excellent btw). Last night, as the Romulans, I took about half of the Federation’s territory in a war including Earth and genocided about 50 billion people. Everyone except for my cousin species the Vulcans. They get to be slaves.
Infinite energy is cheating. Same with travelling backwards in time.
My intuition tells me the universe doesn’t allow cheaters.
But then I’m just an evolved bag of water cells clinging onto a clump of rock so what the fuck do I know?
