I suggested other terms, like 'depiction'. A depiction (IMHO which I hope is not too controversial, but who knows, lol) SHOWS something. It might be used to recognize what it depicts or even extract some traits (IE if I look at a picture of your Maserati I learn that it is red and has 4 wheels, etc.). In my opinion this is a more useful word to use for most of what goes on in RPGs than simulation.Some people just want to define what the word simulation means for everyone else. That if any aspect of D&D does not follow that strict definition, than no aspect of D&D can be considered simulation.
Nobody has come up with a better alternative, so I will continue to consider D&D a necessarily crude simulation of a magical world.
