I doubt the game is as finished as it seems, especially with regards the procedural animation--creatures tripping over their own legs and such (although that would be hilarious

) On a tangent, I wonder how different the procedural creation and population of worlds (disregarding the effort in putting stuff together that looks "right") is from, say, the random map engines of the Age of Empires games.
If you watched the 1up pre-E3 video with the spore stuff at the end (I say that video because the quality is a lot better

) the graphics are still pretty glitchy, I don't know the right words, but where you zoom in on a planet and the water and land clip each other back and forth...
Hopefully that made sense....sorry if it didn't.
