Moons of Elsweyr added its own zone content, and a good amount of it too. It also broke my save, forcing me to go back to an older save and lose TONS of progress.
Edit: Just saw this in the FAQ area:
Quote:
The uninstallation of Falskaar is NOT supported. It's simply too big. Treat Falskaar like a DLC, and do NOT remove it during a playthrough. Only remove if you are starting a new game. To remove (Only for new game) simply delete "Video/Falskaar_Intro.bik", "Video/Falskaar_Outro.bik", "Falskaar.bsa", and "Falskaar.esm". Failure to follow the above conditions will likely result in serious, irreversible damage to your save and is not recommended or supported.
Tread carefully. If you use this, I'd recommend forking a save specifically for that content only.
