I love this thread. Reminds me of Nguyen's Games: Agency as Art. I especially love the idea that both losing and winning (and ideally all end conditions possible within the model) should be experienced to fully understand the game.
following up on the last thing, i thought i'd talk a little bit about how i see systems of rules as art objects. basically, to me, a game system is an art object, but it is also an art object which can only be fully apprehended through play. the structure may be visible, but the themes will not be.
