Oh man, one of the creatures my brother made (Called 'Epic Ugly'), the game came across it and made to be absolutely huge; was by itself and ravaging every nest it came through, Everytime it walked the screen shook; It was crazy. Spore is as good as I expected.
Edit: It has 1000 health and is made out of Rape.
Edit2: Ahh, the 'Epic' is only put infront of the big ones. Well, and Epic Gosse dropped out of a UFO and onto my borthers new nest.
