I was initially going to say I wasn't excited for this game, because I think it will be much like Spore in that the planets simply don't feel big and unique enough.
Howeeeveerr, I figured I should check out some more videos of the game and I have to admit I am pretty excited now. I don't really like the way every single planet I have seen thus far has had a very boring sky. Like it's very foggy-looking and there aren't really any clouds or anything like that. And the way the sky sort of blends in to create the foggy effect that restricts your view distance I personally feel takes away from the sense of scale. Then again, there will be infinite planets, so maybe if I get the game and go exploring, I will find my perfect planet to stick around and explore!
I will rummage through all the gross looking purple-grass planets to find earth's prettier cousin!
I'll most certainly be giving this game a try at some point. Once I get something other than my MacBook <.< (seriously, don't get a Mac)
