:Although both this game and Simearth have "evolution" as a theme, that's about where the similarity ends.  Aside from the vague notion that creatures change over the course of play I don't see any connection between the two games. 

 :Now Civilization, on the other hand, does possibly bear a resemblence to the final phases of Spore.  However, it's really just speculation how closely related the two are, so it would be premature to mention the Civilization computer game in this article. Therefore I would suggest not yet mentioning the computer game Civilization in this article, and would leave out Simearth altogether.
