At this point will FFXIV collapse if all mods and third party tools disappear?

[MistakeNot]

It's not just mods. It's also the community created resources. Who will keep playing the game if all FF14 Discords disappeared suddenly? Almost no one is playing the game because of the game. They are playing it because of what the community has created. Just think of content like Baldesion Arsenal. Almost no one would ever do it if the Discord dies. Or Savage. No one would do it if there are no guides. We owe far more gratitude to the community than to the developers.

You are mostly wrong - the community exists because people are playing the game, not the other way around.
But be that as it may - how is FFXIV different from any other MMO in this regard? Players use community-made information for all of them - and for plenty of single-player games as well.
