Amnesia 6th anniversary community project (?)

[Mudbill]

I think you misunderstood me. Just imagine a mod, like White Night for example, but which also shows up in Amnesia's custom story list. The player can start it from Amnesia (if they prefer or only know how to use custom stories), or they can start it as a standalone mod to get the extra details, like the menu and other things. They won't need to do anything differently in terms of installation.

Other than possibly being "unnecessary" I don't see any drawbacks in doing this.
