Im pretty sure the dlc is big, http://www.elderscrolls.com/oblivion/dlc/ shivering isles adds 30 hours of gameplay apparently. I havent played them yet I got busy modding the game for 2 days then I got distracted by another game I bought
Shivering Isles and Knights of the Nine are included in both versions of the game, I'm asking if
Fighter's Stronghold Expansion, Spell Tome Treasures, Vile Lair, Mehrune's Razor and much more.
are worth the extra £1.70.
Inb4 it's less than £2 - I can buy a game for that much during sale.
