@Crimson Paladin I don't get how Gothic 3 looks good. It looks worse than Oblivion. And the landscape is all flat in the background.
At least for me and my Radeon HD 5770, Gothic 3 looked like a giant road texturing machine had passed over the whole world. But it had topographical (not geological as I said before; at the time I couldn't think of the correct term) features, like cliff faces and crags, the layout of the land was much more interesting. Oblivion and Morrowind both lacked decent topography, the layout of the land was just bumps and smooth hills with rocks to make it look more rough. I recall not being very impressed with the mountains in either game.
Doesn't make it a good decision. Do you know how many cliché Middle Earth style gameworlds there are? TES was great for not just being another one of those RPG's. Even in the earlier games. I can forgive the likes of Morrowind, since, who would like walking around one big hellish landscape for hours on end? But Cyrodiil was perfectly fine the way it was in lore. The change was completely uncalled for, and we got something we've seen a million times over.
Geographically, though, it makes no sense to put a jungle next to a polar climate. You'd need a sizeable temperate zone in between.
I think the biggest thing that would have improved Cyrodiil, in my opinion, is more interesting topography, something that would also serve as an improvement from Morrowind.
