So, I just purchased Oblivion about a week back. I'm playing through it for the first time and I'm curious about the DLC. I'll be getting shivering isles and any others that bring additional quests. My question is more directed towards the smaller add-ons. (Horse armor, warlock tower, spell tomes etc.) From the descriptions on Xbox live it sounds like their just extra locations around the map. I'm wondering if they actually bring anything into the game that's useful or if they're just extra locations with some loot or something along those lines. Just looking for informed opinions before I go spending my money. Thanks guys.
