I just got Spore and it is really awesome. I love the creator because, with the whole TAB button secret, you can make really in-depth builds. The TAB button, held down when clicking ona part of your creation, enables extra handles to rotate the object with. Post your creations, achievements you have, cool things you have built/found, techniques, etc. etc..
Oh! Almost forgot, post your username too!
Mine is: TomTheZombie
(an old name I used to like :D)
