The Legend of Zelda is focused with the Triforce, you cannot have one without the other. In every zelda game, there is the triforce, no matter what.
This is very false. The Triforce is not in every game and is certainly not the center of attention in every game.
The Triforce is not at all involved in the stories of MC, FS, FSA, OoS, OoA or LA.
MC: Vaati becomes a wind sorcerer and is after the light force (which is widely accepted as being completely different from the triforce).
FS: Vaati kidnaps seven maidens that Link must rescue.
FSA: Vaati kidnaps seven maidens again. Ganon is trying to get the Trident of Power.
OoS: Seasons are out of whack. Link must try and save the Oracle of Seasons and stop Onox.
OoA: Time is out of whack. Link must try and save the Oracle of Ages and stop Veran.
Linked OoA and OoS: Link must do one of the previous 2 things and try and stop Ganon from being resurrected (and ultimately defeats a brainless Ganon).
LA: Link must collect 8 instruments to wake the wind fish.
Literally none of those games have anything to do with the Triforce. The only thing those games might have to do with the Triforce is that the Triforce symbol might be on a building or piece of equipment but that's it.
