If you clearly define the limits of the supernatural, that is, assign numerical values to all available abilities in the game, then it won't turn into nonsense.

-- Revan, well, let my people have the technology to travel back in time by one minute. That's perfectly balanced!
-- Revan, what are you even talking about? A minute hasn't even passed! Why can't I rewind a nuclear war?
Not literally, but I'm afraid that's how it will be.
