Please let me reiterate since the thread's gone back to "I don't want deathmatch AI": what we know is the AI will play to win and will be more human like. If "every UU will have a non-passive, unique bonus" means "legions can build forts and roads," I don't see how we can take either of these to mean "whenever you get close to winning everybody will dogpile on you" and "everybody will betray you all the time if there's any possible, marginal benefit to doing so." Yes, it's possible that's what it means, but I see no reason to believe that's the case other than just to find another thing to complain about.
You can intercept spaceship parts now, since they have to be manually moved to the capital. As for Utopia, you can certainly capture the city building it, but I'm not sure if you'll be notified of when/where/if it's being built. Is there perhaps confirmation on either a notification or an ability to see enemy build queues (like, for example, with airplanes?)
But how does the human player avoid a space/utopia loss? Espionage is gone.
Capturing the AI capital?
