you dont know what you're talking about... Leaving a ship above a neutral planet will not increase the planet's favor to your side.. The planet will not join the empire/rebels if you keep that ship above that planet antonius, something else must've happened in that system for the planet to join you! And another thing... Two posts earlier, someone mentioned a tactic to take control over a complete system in a short amount of time.. The tactic in which you have to sent a diplomat to one planet, take it over, cancel the mission, take over the next planet, etc... The fact that all those planets are sill not 100% to your side is very dangerous, bcause when playing against a strong AI or multiplayer opponent, your foe only needs to converse one of those planets for the whole system to abondon you! Happened to me twice, not very smart... Make sure that, if you take over a planet, it at least likes you 90 % so you can safely continue taking over that system.. That way you wont lose an entire system at once, if you play against a smart foe...
