Im about to buy Oblivion, But I need help

Someone has probably created this topic before but I don't care

I really want to buy Oblivion, and I heard theres expansion but when I looked it up it seems as if theres 1 expansion and 2 different games so I am confused, could someone list all the EXpacks for Oblivion for me and sort this out, greatly appreciated

There's only one. Shivering Islesachilles614

there's also Knights of the nine but i dont think thats an expansion

What is "Knights of the Nine" exactly? Falconoffury

It's one of the many modules you can purchase off the oblivion website. There are many such modules but only one expansion pack: Shivering Isles.

Knights of the Nine is just a retail version of all the mods you can pay to download on the Bethseda website. I think it also includes a extra "quest line" thats sort of a good version of the Dark Brotherhood.

Shivering Isles is an actual expansion with a new place to goto with all new voice acting and such.
