Whatever part of Tamriel they choose, I hope it recaptures the atmosphere I got enveloped in when I first fired up Morrowind.
Not in the foreign world (as opposed to clichéd fantasy settings), but in the feeling, that you actually are a friggin' nobody - an outsider, an unwelcome presence, an n'wah, not another would-be generic hero (although you eventually became one). You entered a place with deep rooted traditions, generally uninviting to foreign people. A dark place, a bloody place - a believable place. It was a great environment for role-playing, if one chose to. The lore, the culture, you actually saw that the developers put their minds to it and crafted the world (almost) from nothing, whereas Oblivion was a total disappointment in this aspect (I guess only the Radiant AI and some other mechanics, along with graphics, were upsides).
Elder Scrolls is an awesome universe, full of mythology, conflict, religion, betrayal, legends, fleshed out cultures and civilizations, mysteries - whatever, you name it. But, to me, the only game that managed to build on this unique background, was Morrowind. I've mentioned my opinion on Oblivion. Skyrim just upped the epic fantasy ante, which isn't exactly a bad thing, but it did so in a way, that made it seem like just another woo-hoo open-world RPG, only set in one of my favourite universes.
Mind you, I don't exactly need a pessimistic, dark, cruel world (although it may seem I prefer so, but - bear with me on this - imagine, what exactly is the appeal in a show like Game of Thrones? or Sapkowski's Witcher?), I just want a believable atmosphere, or at least a glimpse of it.
But, since games today are being made with casual players in mind, it all is just a one man's dream.
So... Black Marsh I guess...
