18 minutes ago, Bertie Wooster said:IIRC, Player 2 would have to re-invade, because they need at least 1 GF of their own on the planet, in order to control the planet.
Step 1: Player 1 invades the planet. All GF on the planet are Player 1's.
Step 2: Player 3 invades the planet. All GF on the planet are Player 3's.
Step 3: Player 2 needs to re-invade the planet with their own GF. If Player 3 and Player 2 are cooperating, I think there's a way for Player 3 to "surrender" to Player 2. @clontroper5 and @idjmv did something like this with planet F.
Edit: I don't think it's possible to leave a planet "unoccupied," I believe the rule is you have to have at least 1 GF on a non-Capital planet.
That was my understanding too, thanks.
