And that's one of the myth that should die...
In "GNS" words : Exploration is "essential", simulationist play is not.
Weird, the second line there didn't appear in the post, but it did when I hit "Quote".
Anyway, he's right for the definitions of the words that I imagine he means (howandwhy99 seems to be using the worlds in their original meanings, devoid necessarily of the especially constructed GNS language . . . care to clarify one way or another, howandwhy99?).
Anyway, I think he's right. Roleplaying games, no matter how you play them with respect to GNS, are about imagining things, usually human beings or humanlike personalities in some kind of interesting context. I guess it's possible that some D&D players are so divorced from their characters that it really is just the numbers and mechanical parts being moved in a very complicated dry state machine, but for the rest of us, imagination comes in there somewhere.
Using ones imagination is an act of simulation -- your mind may be the computer running the simulation, which is awfully squishy, emotional, and creative compared to an actual computer or mathematical model, but it's doing the same work: Taking as inputs information about the in-game situation, and then outputting character decisions. The model used could be knowledge of the game system or just as easily knowledge of reality, or the reality-like place in which the game is set, which could be devoid of game rules as such.
