OP is either a cynical ass or a troll. There.
As a cynical ass myself, I resent this notion. In fact I'm quite offended that the OP and I have been lumped into the same category. You sir, have made me sad. :<
It's curious to note that for all his whining about Skyrim's art direction and design, the OP has still not bothered to reference an image representing what he thinks would be appropriate to his criteria, despite being prompted multiple times to do so.
Skyrim isn't the prettiest game in the world, but it's unique and looks fantastic considering the sheer scale of the world, it's also nice to see that the major cities don't recycle architectural styles either, there are obvious aesthetic differences between Whiterun and Windhelm for example or even the huge differences between Riften and Markarth. Stepping into a new city in Skyrim is so different to how it was in Oblivion, I could understand the OPs complaint if it were directed at Oblivion, as many of the cities looked similar but the immense level of diversity displayed in Skyrim makes it difficult for me to comprehend exactly where he's coming from.
It seems that he's unable to realise that the alien style of Morrowind, with it's immense mushrooms and vast ashlands is supposed to be inherently inhospitable to 'outsiders', different to the perception of what is normal or standard in fantasy. Skyrim on the other hand is far more grounded, filled with grit, a hard land filled with tough people surviving through grit and guile alone. Skyrim is meant to look rugged, but that doesn't mean it looks ugly, far from it. Skyrim is easily the best looking RPG in recent years, it's design appropriate to the styles of a medieval time period, yet retaining the lesser trappings of a fantasy world that make it so magnificent. I may have grown bored of the game, but I have not grown bored of the world, if I could wander the roads of Skyrim undisturbed, I would do so for hours.
Don't feed the trolls kids, and remember; they regenerate health when wounded.
