I know it's a tenuous link at best... but this game really reminds me of "EVO Search for Eden" which was an old game on the SNES with a similar concept... You start out as a fish, and you eat smaller animals to gain points, you then use these points to evolve your character. The game went through several stages (Fish/Dinosaur/Bird etc) and was great fun! Hopefully SPORE will be just as - if not more -fun!
