A game is, by rule and definition, simulated. Whether physical or abstract, games can serve as entertainment in its purest form, be educational or both. It matters not if you're running the virtual runtime environment off a refurbished hundred dollar laptop or one of United Airlines' state-of-the-art A320 simulators in Denver. Understand that a simulation will always be a game and vice versa. What's of importance is what you make of it, really.
