CHC teaching tools - Verbal "Planning"

I recall sitting around with a neuropsych type a number of years ago disucssing the Tower of London test as a measure of planning (forward thinking). The conversation moved to a possible verbal planning test. he mentioned the idea of the classic game "20 questions." Today, over at the Download Squad, I noticed a post about a new version of this game. Check it out and see what cognitive processes you think are involved.
