New info:

"Once an organism has evolved enough to become sapient, the player enters the tribal stage of “Spore.” Players can join with others to form tiny communities and outfit them with weapons or musical instruments for their interactions with other tribes"


" Once the tribe reaches 20 members, players can continue to the civilization phase, where they build and refine their cities in a manner akin to that of “SimCity.” They can then leave the terrestrial sphere on spacecraft and go into the galactic phase to conquer other planets in the final portion of the game.
