Spore, anyone?

Well it was generally more realistic. It had more stages (for example sea stage) It was much more of a survival... If you were a predator. You would need to drag your victim's body to somewhere safer to eat. Because you could be attacked by larger predators yourself... Also there were no "nests" and you weren't suppose to "sing" horribly to other critters for whatever fucking reason.
