You have to find a character in the game , who will activate the Quest. No spoilers here, sorry.
You get the Shivering Isles expansion but the ONLY DLC it comes with is Nights of Nine.
I don't understand the question. Oblivion Game of the Year edition came with Knights of the Nine and Shivering Isles. and the only way so far that is tried and true to activate it is to have xbox live and get the update for it
Yes...game of the year edition contains both expansions (Shivering Isles/Nights of the Nine)
hold down block and click activate
You never become an actual god in Oblivion.
Ninety-Nine Nights happened in 360.
Ninety-Nine Nights II happened in 360.
Ninety-Nine Nights was created on 2006-04-20.
Ninety-Nine Nights II was created on 2010-06-29.
Ninety-Nine Nights Original Soundtrack was created in 2006.
Steam has it, with Knights of the Nine also.
For Xbox im 95% sure that its not possibe, except with nights of the nine you might be able to when your falling from the sky. On the PC there are various mods that allow you to.
