So, Steam has a 75% off sale ($5) for The Elder Scrolls: Oblivion GOTY Edition, and it has made me wonder: what are the differences/improvements of Skyrim over Oblivion? Of course, there are double-wielding, a more dense world, and randomly generated structures in Skyrim, but what is/was so great about Oblivion? Is Oblivion's world really as barren as people say it is?
