PathFinder : I don't think the AI can handle the Shadows and Vorlons if they aren't allowed to colonize. Even under Human control that rule would make it very difficult to expand. Probably even worse under multiplayer - Vorlon fleet is spotted approaching other players world, other player decides he can't get enough reinforcements there in time and just abandons the planet. The Vorlon player then has to travel deeper into the other players space while the other player has dozens of planets able to produce defences.
