Meh, it seems like some of these suggestions are way too deep. It's UNIVERSE sandbox, not earth sandbox.
But, the position of continents does influence tidal friction between the earth and moon (Right now, we have a big pacific ocean, so tidal waves have a long distance to travel, which makes tidal friction stronger). When an ocean is bigger, the tide bulge travels faster than the moon, so the moon tries to pull that bulge back, which also pulls back the rotation of the earth. That's why astronomers don't know how close the moon was to earth 4 billion years ago, it's too unpredictable. So if US ever does get continental drift on planets, the distance between coasts could be used to simulate tidal friction (The moon's rotation slowing down until tidal locking, and getting farther away from earth, while the earth's rotation also slows down) Although, these things would require the time to pass really fast
