I'm pretty deep into my latest game of Galactic Civilizations 2: Twilight of the Arnor, and major races are starting to drop out of the game. Except, in Gal Civ 2 instead of sticking around until they are totally eliminated, the major races will surrender to a friendly civilization, deeding their planets over to that friendly civilization.
How does the AI determine who to surrender to, and is there some way to game the system? Daddy wants more free planets.
