Does oblivion game of the year edition PC come with any official pluggins- e.g. horse armour?
The Game of the Year Edition includes the original game as well as the Shivering Isles and Knights of The Nine content packs, but not the other downloadable content. If you buy the Knights of the Nine pack it has the other official plugins, such as Horse Armor and Orrery, on the disc. I have no idea why they chose not to include the plugins in the GOTY edition.
