In the last game(s) i played, i had several planets, where no field was free: i had colonists there, but before they could do anything good, i had to clear some fields first. It was always rewarding, but i had to invest a lot of energy. So, i don´t see the problem. And yes, i play with Gullies Planet Mod as well. But i do not have any problems with that.Sure, but those can be cleared.
