Well that may be due to the fact that realism is sort of the only requirement for a simulator.
There is sort of a difference. Realism is a property of media and art. While a simulation is a tool that emulates a system. Simulators/Simulations don’t have to be games, they don’t have to be computer programs, they don’t even have to be physical as there are simulations that are simple mathematical formulas.
So realism is a property of a representation and a simulation is an object itself.
Of course to emulate a system that emulation needs to be realistic. But they are very different things, you can never call a painting a simulation but you can call it realistic.
Realistic comes from realism which is an art/media category that the representation is physically correct… Nothing more nothing less. It doesn’t have to be accurate or historical in any way. One of the most famous examples of realism is a painting of jesus in front of a medieval french castle. Since every tree building and person in the picture are painted physically correct it is realistic, while it is utter nonsense at the same time.
Realism and simulators are clearly defined.
A Simulation is a system that emulates another system faithfully, to a degree that you can train someone on that system or make experiments with that emulation which results hold true for the object that is being emulated (think of digital crash tests).
Realism is an art category where every media falls under where the portrayed objects are physically correct… But again they can be completely inaccurate. So something like a car that is controlled by a joystick is realistic as long as the mechanism hiw thus Control works is physically viable.
All you need to do is apply these Definitions. Does WT GF RB fall under the art/media category Realism? No since mouse aim isn’t physically possible in the real world at least nit the way it works in WT.
Does WT RB GF emulate a tank to a degree you could train a tank crew? No.
The thing is a simulator is even stricter tjan expecting realism. Since our joystick car example would be realistic but not a simulation of a car, since it won’t help anyone to learn how to drive.
Since simulators are always emulation if system you always have to say what they are a simulation of.
DCS isn’t a driving sim but a flight sim. The system emulated is flight.
Just saying dcs is a sim is meaningless, because without a system that is emulated simulations do not exist.
The correct response to “X is a simulation” is always “a simulation of what?”
There are no general simulations, there are only simulations of X. With X being any imaginable system.
Otherwise everything and nothing is a simulation. Since there is a timer im RB GF that works, it is a simulation of a timer… Of course that is useless as a game but it makes it a sim of some sort.
That’s why the concept of a simulation without saying what is simulated meaningless and stupid.
