I’ve always pondered over the terminology and I really think it needs to be re-ramped in light of exactly what you say. When you search the internet you will find the full range of descriptors. Game, simulator, flight simulator game, flight simulator, simulation video game etc. Clearly, if aviation flight schools use the program as a teaching tool with FAA approval, it is clearly not a game. On the other hand, Microsoft Flight Simulator is being published by Xbox Game Studios for Game Pass subscribers.
