For a bit of context, final fantasy 14 sucked when it came out. Yoshi P came along and had a team start working on remaking a new version of the game (A Realm Reborn 2.0).
He also had another team continue to work on updating the existing FF14 to show appreciation for the current player base.
In these updates a red dot in the sky grows bigger and bigger and in the final moments before the game is destroyed, the players are shown what is now the trailer for A Realm Reborn.
It is a whole 8 years later in Endwalker that we are told through the story of the true meaning of the lyrics in the song played in this trailer.
Anyway, just wanted to share a beautiful gamer moment. Have a nice day!
