Besides the obvious benefit of being awesome, I think there could be a more serious benefit to this. One extreme failure mode when imagining the behavior of an AI is not merely to fail to imagine it as being superintelligent but to imagine it as being less intelligent than yourself, as not doing things you could think of (a la That Alien Message). A game that consisted of you, the player, needing to come up with increasingly complicated ways to trick these 'shopkeeper' agents could illustrate this pretty neatly.
