i played around with the noclipping thing in the console, and the problem most mentioned that i've seen is that when you get over cities, they wouldn't actually be there because the cities are in a seperate world that's loaded when you walk through doors
but you can still fly over it and it looks fine as long as you don't get too close.
another problem is moddeling. from what i understand it's impossible to model in oblivion, for now, right?
but there's gotta be a way around that soon enough...
so what if someone took a regular horse, and somehow modelled a set of wings onto it. whenever you road it, the wings would rest at it's side and it'd work just like a regular horse, however, if you got it a decent speed, and jumped, it'd spread it's wings and fly. i'm not sure about feasability, but if someone could do it, it'd make travel fast enough that you could remove the fast travel option from the menu, even if it's a cheap way of doing it, like tricking the game into thinking there's always an enemy present.
but that could bring back the feeling of travel, and generally make the game much more enjoyable if you ask me. but hey, that's my two cents.
so does anyone know if there's a way to model in obivion yet? or if there's one on the way?
