" All reality is a game. Physics at its most fundamental, the very fabric of our universe, results directly from the interaction of certain fairly simple rules, and chance; the same description may be applied to the best, most elegant and both intellectually and aesthetically satisfying games. By being unknowable, by resulting from events which, at the sub-atomic level, cannot be fully predicted, the future remains malleable, and retains the possibility of change, the hope of coming to prevail; victory, to use an unfashionable word. In this, the future is a game; time is one of the rules. Generally, all the best mechanistic games—those which can be played in any sense ‘perfectly,’ such as grid, Prallian scope, ’nkraytle, chess, Farnic dimensions—can be traced to civilizations lacking a relativistic view of the universe (let alone the reality). They are also, I might add, invariably pre-machine-sentience societies. "
