"Or, in a diffirent formulation of the legendary author of Sim games Will Wright, "Playing the game is a continuous loop between the user (viewing the outcomes and inputting decisions) and the computer (calculating outcomes and displaying them back to the user). The user is trying to build a mental model of the computer model.""

"Unless you design, build, experiment and test in the real world in a tight loop, you can spend a lot of time on the wrong problems" Yep.
