yep I dont want AI, I want human brains controlling things. That is why I have NEVER been into any game that doesnt allow me to interact with other humans. I dont like beating on a machine that has set rules and does this or that when I do something (cause and effect). I like playing people, and knowing that I am either better or worse at the game than they are.
Well spore is about playing god and evolving your faction/creature, i don't think you would like to have to wait every time your opponent "pauses" the game to design a new tank or building.
I don't think the RTS style battle side of it is advanced enough to warrant online PvP mode, since it is not its main aim.
