Since this is the Future Ideas forum maybe I could post my idea here that would be a great addition to the game imo. So Venus... We all know that Venus is in the inner edge in the Habitable Zone and we also know that Venus is so hot because of it's thick CO2 atmosphere. And I was thinking can't the dev's make it another Earth-like planet that needs atmospheric cleansing to be colonizable? I know there would be 3 planets for the Terran Alliance but other civs already have 3 worlds in their home system.
Long story short Venus should be colonizable but requires the atmospheric cleansing tech imo.
