I'd argue that while the Morrowind sky was more attractive, Oblivion's looks more realistic in that comparison, if you look up at our real life moon, it's not nearly as huge as the moons were in Morrowind, nor will you be able to clearly make out craters just viewing it with the naked eye, for example, but that's kind of the problem, really, I don't need my night sky to look realistic, after all, the Elder Scrolls is a fantasy world with its own stars and other celestial bodies that are very different from the real world, so this is one area where I think Bethesda really has a lot of freedom to use their imagination. It's going to look pretty strange if the human races don't look anything like real humans, but the night sky doesn't have to look like what you'd expect to see if you looked up at the sky, as long as it's still plausible, and I felt Morrowind's night skies were mostly plausible for a game taking place in a world with its own distinct stars, except for how huge the moons were, because if the moon got close enough to the Earth to appear that big, I think we can safely say that the effects of it would be felt, but given what the lore has to say on the nature of the moons in the Elder Scrolls, I'll give Bethesda a free pass on that one. Who knows how the corpse of a god effects the tides of Nirn, if at all?
So yes, I don't mind if Bethesda takes a few artistic liberties with the sky, as long as it doesn't look too out of place.
And it boggles the mind that so few people who played SI actually got the crucial fact in that it takes place in Sheogorath's realm of madness, and not a real physical space on Nirn.
That's true, we're not going to see night skies like the ones in Shivering Isles in Skyrim, because that's not Nirn's sky at all. I like the sky in Shivering Isles, mind you, it seemed to fit the place, but I'd no more want to see it in Skyrim than I'd want to see giant mushrooms.
Grey, cloudy, overcast days only occasionally broken by few days of sunlight...
Sounds extremely boring and monotonous to me, no thank you on that one.
