I agree that game designers are also trying to make a system that's a good game. But I do understand GP's point here, insofar as the designers have to build the system within a certain frame of reference. As an adjacent example, City Skylines is a pretty fun city builder. A huge simulation, down to very complex traffic models. You can build sprawling cities with a bunch of highways. But it's extremely hard to build anything that replicates old European cities, or denser cities like in Asia, because your smallest useful road is very big in relation to the buildings. The tools given to you basically point you directly to American-style zoning that leads to suburban sprawl and huge highway systems. In a sense, that's the point of the game (to make you fight traffic), but it's difficult if you are trying to build a certain kind of city that we know exist and are, in fact, "better cities". The simulation presents a certain worldview of how cities are built.
