I would love to be able to do long-distance walks in a world like Skyrim. Long-distance hiking is my favorite form of recreation. I've hiked chunks of the Pacific Crest Trail and the Appalachian Trail, walked the entire Ring of Kerry all in one go, as well as some shorter walks in Ireland, and about half the Camino Santiago de Compostela. I have a lot more I'd love to do, including one across the Gobi I hope to someday be able to afford. A few things I've never been able to escape though, even on these walks -- the sound of trucks and other construction machinery, the distant hum of highways, cars going by, sometimes stopping to ask if you need a lift (almost exclusively in Ireland) then being unable to fathom that you are walking for fun, airplanes overhead, cell phones ringing, power lines buzzing . . .
The modern world has places as beautiful or more so but you just can't get away from the noise and machines. In Skyrim you can start from anywhere and head any direction across pristine, unbroken countryside. That's what I'd like. Preferably with access to modern medicine and no bandits though.
