Personally I love the forests, in fact the first thing I am going to do (When I get a chance) is go wandering around for hours. Maybe do some hunting in the process.
So what about the rest of you? What about Oblivion do you love the most?

For me.. Its just that its a whole new area to uncover. I love discovering secret ruins and caves. One of my fondest memories of Morrowind was from the very first day. I was just wandering around outside Seyda Neen and decided to swim in one of the little ponds. I found a cave entrance underneath the water and decided to check it out. I spent an hour taking breaths of air in air pockets just so I could harvest all the little pearls I kept finding in the seashells there. Its just that sense of discovering new things the very first time that I am going to enjoy so very much!
