Possibilities for combining the game object and the simulation object are limited and precarious. It is certainly conceivable that the output of a simulation might serve as the input to a game. In such a case, the simulation portion of a game might prove capable of spinning along and churning out material effects without need of human intervention, until, as governed by the game rules, the game player chooses to stop that simulation from simulating. During that intervention, the game player might be able to play a game. Yet, when simulation and game are so distinctly layered in this fashion, though they may function in combination and cooperation, that layering seems more indicative of their differences than their similarities.
