So , hello i'm new here and i have a question , how do you interview alien ? I have captured some of them , except that I was afraid that if I put the aliens in my capital , they die because it was not the same atmosphere or they mingle in my population suddenly I dissected the aliens to know their preference and I terraform a planet for them then I drop them on the planet and I put my spy team but nothing !! How it works ? I'm lost and another question, how enslaving alien population?
