I appreciate the production quality and clarity of your document. As you indicate in the teacher's supplement, the game could be used or adapted to explore a number of different ethical theories in addition to Mill's utilitarianism. Divine command theory in particular comes to my mind, considering Plato's Euthyphro and Kierkegaard's discussion of the binding of Isaac in Fear and Trembling.
Do you think the consequentialists' arguments may change or even challenge each other depending on their particular readings of Mill and/or consequentialism in general? I wonder what the responses to various calamities would look like with one "rule consequentialist" and one "act consequentialist," for example.
