Are engines the power plants of the whole ship, or are they tied to thrusters? Exactly how are engines used?asked by Chaos Griffin

Well, I think maybe the best way to think of engines is it is the power plant of the ship. So that is generating the power. So it can be a fusion engine, it could be an antimatter engine. And it's generating the power for your shields, it's generating the power for your life support, your avionics, your weapons, and it's also generating the power to be expelling the mass, your fuel that you've stored, to move around. And that gets expelled through the thrusters. And that's where you would be fueling up with, say, hydrogen or something. And so the power plant does all that, so that's really what the engine is.
