Oblivion's expansion pack, IMO, is downright awesome. Although the land is only about 1/4th the size of Cyrodill, every dungeon has it's own personal touch. I've come across a few already that even have their own stories to them (no sidequests, just neat stuff).
New traps too. One similar to a pessure plate that makes spikes shoot out of the wall. The best so far was in one dungeon / fort, which if you tied to cross a bridge, a statue would shoot 8 randomy targeted electric shots at you.
And of course, my favorite line by Sheogorath:
"A celebration is in order! Cheese for everyone!. No wait, scratch that, cheese for no one. Still a celebration if you don't like cheese, though."
