There's an episode of Star Trek TOS where they discover a pair of planets that have been at war forever. They have done away with actual physical warfare, since that would damage their infrastructure to unacceptable levels, and instead just simulate the results of bombing and tell each other who died. Everyone who the computer determines dies is notified and then shows up to the war facilities to be disintegrated.
