Game Trailer's timeline insn't very well constructed at all. There is a lot of information that they made up in that video to place certain games in certain places. So I don't agree with it at all.
Here are a few things they screwed up:
It has never officially been confirmed that Gustaf, the ancient King of Hyrule who's ghost comes to you during MC, was the Hero of Men mentioned during the intro of MC. A lot of people believe he is, and a lot of people also believe that MC takes place first, but no where during MC has it been confirmed that he is that same Hero. Althought MC may make sense to take place first by other reasons, this is not one that is accurate or factual.
GT's timeline states that after Link leaves Termina (MM Child Timeline or Hyrule A as they call it), that he tries to return to Hyrule via the sea, where he then gets shipwrecked and ends up on Koholint Island, where Link's Awakening takes place. All of this is made up. The true placement of LA was meant to take place after ALttP, where LA's manual directly talks about Link leaving Hyrule to clear his mind and search for enlightenment incase Ganon is to return. Also, it is clearly shown at the end of Majora's Mask that Link is back in the Lost Woods, where he is riding Epona.
They also place LoZ after LA, in which they say that Link returned to Hyrule to find that "Ganon had won the war". The question here is, what war? GT never makes any reference to a war taking place in Hyrule on the Hyrule A (Child) side of the Timeline. This timeline was also created before TP was even released. In TP, we find that after the events of OoT on the Child Timeline (Hyrule A), Ganondorf was sent to trial for attempting to take over Hyrule, and ended up being placed in the Twilight Realm after an attempted execution.
One thing that they do get right is the placement of AoL after LoZ, but placing both after LA is completely wrong. GT talks about the actual Legend of Zelda, in which the Prince of Hyrule had his sister, Zelda, placed in a deep sleep. Then, sometime later, the Prince felt really guilty for what he had done, and ordered that every female princess born into the Royal Family thereafter should be named Zelda. This would make perfect sense as to how all the Zelda's have the same name, but are obviously different generations of Zelda. However, it would not explain how if this Zelda, talked about in the manual of AoL as being the original Zelda before any other, was never referenced to in any other game in the series. The supposid sleeping original Zelda obviously remained in the North Castle for ages on end until Link was able to awaken her in AoL, but it seems odd that she is never talked about in any other legend besides AoL, which takes place long after some of the other titles. Also, she is never referenced on the Hyrule B side of the timeline at all, meaning she is still sleeping in the North Castle in that timeline. I don't believe the people of Hyrule would just completely abandon and forget about their sleeping beauty like that.
GT then places FSA after AoL (and completely ignored FS's placement altogether). This makes no sense because Ganon was destroyed in LoZ. The entire purpose of the monsters coming after Link in AoL was to kill him so that they could revive Ganon. Since Link was never killed in this game, Ganon was never revived, and thus could not be living in FSA. Many actually believe FSA takes place before ALttP, which makes more sense. GT actually places FSA before ALttP in their timeline, but only uses Ganon's trident as a backup for that reasoning. To me, thats a pretty weak example of why a game should be where it is, as Ganon has seen to use the trident in many other titles as well. It is more likely that FSA takes place before ALttP because Ganon is still in the Dark World during the game apparently. ALttP talks about the sages sealing Ganon within the Dark World in a previous age, but this cannot be the same time they sealed him in OoT, as he broke free of that seal and went on to create the events which took place during WW, plus, it would place ALttP between OoT and WW, which wouldn't make any sense either, as WW clearly states that Hyrule saw an age of peace after OoT until Ganon escaped. The sealing of Ganon in the backstory of ALttP must be a different time which he was sealed.
And my last reason is the last portion of GT's timeline, which states that the Oracle titles, which we will call OoX, took place at the same time on each side of the timeline. Honestly, I can't figure out how GT was so oblivious as to come up with this theory, as it is proven just by playing OoX that each game transpires after the first one you beat. So really, their order comes in whatever fashion they are played and completed in.
So theres my two cents on GT's timeline. I know its a lot, but they messed up a lot.
