Cool…I dunno is this is really relevant to the discussion, perhaps on a tangent, but something I've always wondered/thought about that never seems to be addressed is that the Triforce seems to have two modes? Because theoretically if someone with an unbalanced heart touching the Triforce makes it split, then that person would never be able to touch the Triforce to make a wish because it always would split. Reforming the Triforce to make a wish seems to somehow nullify this process of splitting?
Another thing to consider with the above is that, does Link have an imbalanced heart that leans most toward courage or is his heart balanced, while also happening to be the most representative of courage at the same time, and his alignment for wisdom and power matches his courage? Does his ability to wish on the Triforce in A Link to the Past indicate anything of the balance of his heart, or why he was able to wield the Triforce of Wisdom in Zelda I?
Just kind of rambling but I find it interesting that the Triforce splitting seems very circumstantial. In the Wind Waker you could say that perhaps it doesn't split upon being reformed because it isn't in the Sacred Realm, but that doesn't explain A Link to the Past nor A Link Between Worlds. Are all people who have wished upon the Triforce in known Zelda lore, those with balanced hearts? Why was Ganon able to wish upon the Triforce in A Link to the Past? What is the criteria that would prevent the Triforce from splitting upon being touched by Ganon a second time, unless it is somehow sentient or records how many times it's been touched by an individual?
Anyway, uh, I think there's a lot more to the Triforce that has never really been examined, and I think this particular aspect of the Triforce's "behavior" should be understood before really saying whether or not it chooses the same people by design.
