Never heard the : Psychotronic term. But all of these are solid advices, that are a big part of modern RPG. Even for a reasonable campaign length. I am surprised that they even still need to be said. Keep the setting consistent (and time), have the player driving the action, and let the player action have consequences. I am less fan of the multiple character, but if even Blades in the Dark and adjacent games push for it, I would see-it as a good practice.
