The game's authors are wrong, period.
Yeah right. You'll excuse me for trusting the people who have produced a game I've loved for more than 40 years over an anonymous stranger over the internet who plays the game in only one way and whose only argument is "but I have win conditions in my game" (because the actual rules say nothing of the kind and I know that you will not produce any convincing evidence).
You know, it's funny, because I have always played the game the way I read in one of the first editions of the game I played: "The D&D game has neither losers nor winners, it has only gamers who relish exercising their imagination."
How long have you been ignoring important parts of what the rules tell you just because they don't fit YOUR vision ? Again, nothing wrong in that, it just goes to show that your OneTrueWayism has absolutely zero support. The authors are not wrong. Neither are you for playing the game in a different way, but you are certainly wrong in calling them "wrong".
I never said playing D&D to "have fun" is badwrongfun (you are repeatedly misinterpreting what I am stating), I said their claims that "winning" D&D is "having fun" is incorrect because there is a defined win/loss state in the rules.
Then prove it. Where in the rules does it define win/loss state ? I expect a precise quote and page number.
