A simulation model played as a game needs to be set up differently. Typically you will want one or two Game Control screen where the user sets up decisions and steps forward in the game. Usually this screen will have some input controls, a forward step button, and some output controls: numbers or a graph. For a very detailed game, input controls and output numbers and graphs might need to be on separate screens that are accessed from the Game Control. The user could also have access to the structure before or after playing the game.
