Even if/as there is no such thing as simultaneity in consciousness, in a game with rules like this thoughts can be neatly divided into "after seeing the results of turn one, and before deciding what to do on turn two," and that is all that is important.
What I said was badly phrased: the assumption isn't true, but if it is being made, that is irrelevant.

I don't know as to how that maps to "simultaneous access to the same information", however, in any computationally significant sense. It's simply a characteristic of the definition of turn-based as opposed to real-time 'games' that you do your processing between turns but during real-time.

I mentioned this in the open thread, and there was a discussion about possibly making one or more "official" LessWrong teams. D_Alex has offered a motivational prize. If this interests you, please discuss in the comments!
