I have a question to the community about capturing razed planets. In my last game I completely eliminated an enemy faction but was unable to capture their planets due to the cultural influence. I could see on the lines between the stars that the culture was still there after the race itself was dead.
So my question is three fold. Why can I not immediately colonize a world that I have razed to the ground. If there is no population left who is going to stop me?
Second after that race was killed I actually lost a nearby planet due to their influence. How come a dead race with no living members left is still having enough cultural impact to steal away my planets.
Third how does a militarily aggressive player quickly colonize recently attacked planets and how do you hold them?
