Personally, while I support the notion that the Triforce always DID have power in the previous games, and how the power manifested with the personalities of Link (Courageous Hero), Zelda (Wise Ruler) and Ganon (Powerful Tyrant), the concept of it losing power over time does give something to ponder about if it affected a future game, or if a game decides to take a meta look on the 'perpetual cycle of the Triforce' over the series.
I already gave my suggestions for what a Zelda game subverting the usual plotlines of the game could look like ( link [http://www.escapistmagazine.com/forums/read/6.833124-Wind-Waker-is-Still-the-Best-Zelda-and-Youre-Surprised?page=3#20370240]), but here are some things I would add based on Yahtzee's points:
First, the villain (still codenamed Mr. X for now), isn't just a genre-savvy villain who kills Ganon before the game, and uses the Triforce of Power to kickstart a steampunk empire that conquers the world before Link and Zelda are even children, but also has motivations based on Yahtzee's long-standing complaints against the Zelda series: the fact all the games were reincarnation cycles of Link, Zelda and Ganon going through the motions of "Ganon wants to take over world, Ganon gets Triforce to take over world, Link (and sometimes Zelda) set out to stop him". This happens after Mr. X studies historical and mythological records referring to this reincarnation cycle (or perhaps realizes it after the cross-continuity explosion of Hyrule Warriors makes him realize the scope of the 'problem'), and concludes Hyrule would be doomed to stagnation because of it. So, he takes out Ganon when his reincarnation first makes his presence known in Mr. X's timeline, and takes the Triforce of Power to forge an empire of his own. However, that's only the first step of Mr. X's plan.
The second step is that Mr. X and his new government suppresses any person or item that in some way mentions the reincarnation cycle, hoping it would prevent the Link and Zelda of this cycle from realizing their destinies this time around. However, this is ultimately a stop-gap measure for Mr. X to continue building his empire and army, since he knows there will be some documents of the cycle that would escape his purging, or people who know enough of the legends but are able to escape his notice. Eventually, the reincarnated Link and Zelda do indeed learn of their destinies, or are taken in by a movement that knows of their destinies, and thus set off to stop Mr. X. But then there's the final part of Mr. X's plan.
The third step involves Mr. X's army defeating Link and Zelda in a way that doesn't just kill them, as that would only send their souls to begin the next cycle, but to claim their souls along with their Triforce pieces, and add them to the great machine that Mr. X used to power his empire - once he added their Triforces and souls of Link and Zelda to those of Ganon, Mr. X would use the concentrated power to destroy the cycle caused by the Triforce, even if it risked destroying his empire, the world, or even all of creation - as far as he's concerned, it's best to completely wipe the slate clean than go through another rerun of The Legend of Zelda.
Sadly for Yahtzee, Mr. X is still defeated by Link and Zelda, and the cycle would still continue - however, the effects of this one game would actually make Ganon less of a villain in future games, as his torment within Mr. X's machine, along with the realization of his role the cycle, would begin to make Ganon question why he's eternally doomed to become a monster that would always lay waste to the world, only to be repeatedly destroyed or defeated by Link and Zelda for his troubles. This may even result in one incarnation of Ganon openly defying Demize (the demon who started Ganon's side of the reincarnation mess in Skyward Sword) to become a genuine hero in his own right, and also leading to more villains in the series in his place - either those who wanted to take Ganon's position as Demize's disciple on Earth, or wanted to follow Mr. X's example of destroying the reincarnation cycle to reform the world in their own image.
Over time, it would result in a situation akin to the Mario RPG series, where Mario/Link is still the hero, but Princess Peach/Zelda serves more as an active ally instead of a captured damsel, and even Bowser/Ganon more often than not joins the heroes to stop whatever new villain is trying to conquer or destroy the world HE wanted to destroy or conquer in the first place. No, it won't completely break the reincarnation cycle, or render the Triforce to useless chunks of metal, but it would finally give the 'meta-aware Batman/Joker rivalry' that Yahtzee mentioned at the beginning of the review. For some long-running franchises you're not a devoted fan of, that's probably the best you can hope for.
