In Skyrim, the 9 Holds are both geographically and politically.
But when I'm playing Oblivion, Cyrodiil seems to separate the geograpically (called regions, example Colovian Highlands) and politically (called counties, named after cities like Anvil and Bravil). Why is it like this, and what is the difference between Cyrodiil's regions and counties?
Have not played much Oblivion, mostly Skyrim ;)
