I tried to avoid extreme spoilers, so I might be wrong. But I think that wtv Jaeju did, it's like getting a "true" ending in a game. That's why after every n5th floor that he did, the tower changes.
I mean, if it's just because he treated the tower npcs like a real person, there must be other people who did the same, right? Immersion is a thing, and not all people would be able to treat everything as fake. But because no one was able to do anything about it, nothing ever changed. Until Jaeju, that is.
Which makes me wonder, if players from Earth did reach the top tower and doesn't get a "true" ending like Jaeju did, will Earth be part of the tower's floor? For getting a "bad" ending?
Again that's just my headcanon, and may not be true at all LoL
