This is not correct. I mean, I learned to play BW from Revised. I only quote Gold because the text is available as a free download from DTRPG.
The stuff that you are asserting is absent from Revised is not.
Page 12: "players take on the roles of characters inspired by history and works of fantasy fiction. These characters are represented by a series of numbers, designating their abilities, and a list of player-determined priorities."
Page 13: "One of you must be the GM . . . Everyone else plays a protagonist (aka, "a character") . . . The conflicts of the characters' aforementioned priorities creates situations for the players to resolve"
Page 19: "As I mentioned in the Introduction, characters are the most important part of Burning Wheel."
Pages 26-7: set out the fundamentals of intent and task (I'm not going to type it out)
Page 32: "If the successes equal or exceed the obstacle, the character has succeeded in his goal - completed the task at hand in the manner that the player described in the Task and Intent sections.
This is important enough to state gain: Characters who are successful complete actions in the manner described by the player. A successful roll is sacrosanct in Burning Wheel and neither GM nor any other payers can change the fact that the act was successful. The GM may only embellish on or reinforce a successful ability test."
This is then followed by the same 3 examples as I quoted upthread from the Gold Hub and Spokes.
Page 34: "Two Directions . . . Failure is not the end of the line, but is a complication that pushes the story in another direction. Failure Complicates the Matter . . . the GM should present the players with the possible ramifications of their tests."
Page 75: sets out "Vincent's Admonition" in the same terms as Gold does, including "When there is conflict, roll the dice. There is no social agreement for the resolution of conflict in this game. Roll the dice and let the obstacle system guide the outcome. Success or failure doesn't really matter. So long as the intent of the task is clearly stated, the story is going somewhere."
The text on the Role of the GM and on "the sacred and most holy role of the players" is identical in both versions.
Gold is cleaner. That's the point of an update. It states the role of the GM more clearly upfront. But there are no fundamental changes (there are technical changes, especially to Range and Cover and Fight! - for Range and Cover I use a mix of the two versions; for Fight! I prefer the positioning rules in Revised to those in Gold). This is borne out by the fact that the commentary in the Adventure Burner (written for Revised) is reiterated almost word-for-word in the Codex (written for Gold).
When you look at the bibliography in revised, and see Sorcerer, Dogs in the Vineyard, The Riddle of Steel and My Life With Master, those are not titles that got lost on their way to an indie RPG party. Burning Wheel is a RPG influenced by all of them. If you try and play it in a way that priorities setting over character, with the GM driving, the game will break down: Beliefs won't work, Artha won't work, Circles won't work, Wises won't work, Relationships won't work, etc, etc, etc.
