Hot damn, this gets really intense all of a sudden. In my first playthrough, I was just waltzing along, playing it like a regular resource management game when suddenly the planet is dying and things start exploding. Then I destroyed the environment and felt like a jerk. I loved it. Sounds kinda boring to say, but I think the UI was really nice. My only complaint is that I don't know when I'm trying in vain to shore up the planet and plant trees, I don't know what kind of building I'm clicking on.
