I have never, in my 30 some years of gaming, understood this as it applies to RPGs, especially in the context of “as the game was intended”. I have run WoD with super heroes, DND in sci-fi settings and monopoly as an RPG. I have yet to find a system that you cannot tweak to do what you want or even just play it out of the box but put a different setting to it. I have seen these, I have no good name for them, shall we try systemic zealot, who believes in some sort of holy grail of “as the designer intended” or “goals of the system”. No one has ever shown me a system that can enforce a type of play and short of a seriously broken system, I doubt there is one. All systems are universal. You may not like the elements that system produces or your opinion may be that the system does not support the elements that you believe are necessary for a setting/genre but those are highly subjective and far from a valid basis for declarations that someone is “playing the game wrong”.
Now, you might say, Bill, my demented game designer, what about the designer, surely, he must know the intended form of play!! First off, stop calling me surely. Second, no, not really. Once you have a game, especially an RPG, it is yours. The designer is irrelevant beyond possible comments or explanations of how he viewed it while writing and playing the game but [b]those views are equally as valid as yours or anyone who plays the game[/b]. I know, as a game designer, I am supposed to push the myth that we are somehow the authority. Somehow, we know what is right for our games and that they can never be played except in the manner we conceive. Sorry to disappoint but no dice…er, diceless…yeah.
So next time you have the urge to tell someone “Oh! you aren’t playing that game the way it was intended!!”, take a deep breath and don’t. Just say no.
Hint for those without a sense of humor: The above may be directed at you, but most likely it is not. If it is (and you would be a weird minority if it did) the good, and I hope it pissed you off.
