Never played Oblivion but I can sympathize with the traveling drudgery of Morrowind. It did, on occasion, lead so some exciting finds; however, following the often poor in-game directions were often frustrating. Now I would say it was like finding bin Laden!

Morrowind was highly replayable. I created a different character for each of the houses and another to just run freelance (literally. I cranked up his speed and made him use a spear).

Skyrim doesn't sound interesting; just a trip to the frozen north.
