Via Greg Goelzhauser I found this fun philosophy game: Battleground God. The game tries to trick you into giving inconsistent answers to various questions about religion, epistemology and ethics. Its moderately fun, but not too hard to find ones way through the thicket to a consistent world-view. (Well, it isnt as long as you read the questions carefully enough, which I almost failed to do on a couple of occasions.) Apparently people who take the quiz endorse, on average, 1.37 contradictions, which must make the dialethicists very happy.
That page has a bunch of other philosophy games here.
