Watching that interview turned out to be a bad idea for me, as it raised much more questions than it put down.
Question 1: Phase skipping.
Ok, so how are our worlds going to be populated with creatures and CIVs? I know personally that given the option I would jump right to space stage. But then what is my base city going to be? How will my creature have evolved? What about the other Civs on my planet?

Question 2: Use an editor anywhere.
What will I be able to do once this creature is made? Just stare at it, or put it down and use it? Will I still have my original CIV in the UFO stage, with a little secondary creature running about?

Question 3: REAL Phase jumping.
Once I get to the UFO stage, will I be able to go down and control one of my individual creatures? I was personally hoping to make a super fast carnivore and go exotic game hunting on other planets, and it looks like that might be possible now...Thing is, we can't tell if they just meant: You can reset yourself in any stage, or you can use one creature and jump between stages (assuming you've evolved up maybe).
