I'll die on this hill.
Sharlayan is where the world building died / will die.

Why bother adventuring, finding out information, talking to locals, talking to people, when:

Sharlayan has all the top tech in the world
Sharlayan has a LISTENING POST INTO THE AFTERLIFE
Sharlayan can invent any mcguffin the writer wants it to invent (Example, teleporter that doesnt need aether manipulation, because Thancred couldn't teleport, CONVENIENT)
Sharlayan has a scholar for every possible thing you can think of
Sharlayan can send gleaners to get anything in the world
Sharlayan HAS EXPOSITION FOR DAYS FOR YOU BECAUSE THEY KNOW EVERYTHING or someone wrote a book on something
Sharlayan built a spaceship, to get into outer space and are planning on using it for further planetary exploration. Yes, that is a sentence

Dude, why bother with any notion of discovery, let alone any fantasy aspect in the worldbuilding anymore when these nerds got us covered in every front.
