This is something that i myself found frustrating when I started out and something I wish new players had complete control over.
The starting menu.
If you purchase the complete edition of the game, you are forced into a situation as a new player where you are given the endwalker intro and start screen, which are both extremely spoilery in terms of where your character is going. And about the characters still present in the game.
This was also a problem for me during Shadowbringers when I started and saw that "ah this character is here" despite being in the point of the story where the character is not present.
It would be great if the game, during booting up asked the players;
Are you a new player?
YES / NO
(Choosing yes will make it so that players experience Intro and Start screen changing as their current data centers character's story progresses. Choosing no, will let players to choose which intro & start screen the game starts with)
So if you say yes, nothing else happens and you boot to your start screen and the game choose it for you. But if you choose "No" the following happens;
"Which intro and start screen would you want the game to start with?"
(Choosing Expansion intro & start screens might contain mild to heavy story spoilers)
Default:
A Realm Reborn
Expansion:
Heavensward
Stromblood
Shadowbringers
Endwalker
