Unless we want the moons and sun spinning around the sky twice a minute, we will never approach the 'time=distance' measurements of Arena and Daggerfall, where crossing a provicne took up towards a month. But Morrowind and Oblivion? The timescales ingame in both helped the world feel larger. If you 'walked' everywhere, in Oblivion it would take around a day and a half, maybe two to go from city to city. Anvil to Skingrad was two days I believe. I don;t think Morrowind was much different.
In Skyrim you can walk from Riverwood, to Whiterun, to Windhelm in a single day. Easily. It makes Skyrim feel smaller than it probobly is at times.
For my own immersion I need to 'fix' it. I think, perhaps, Oblivions timescale may be the one to match, but i'm not certain. I always felt like I had time to do things, but there was a limited ammoutn I could accomplish in one as it should be.
What timescale do you prefer, and msot importantly... why?
Oh, and if someone would be kidn enough to mention what I need to match Oblivions that would be appreciated.
