What I've always wanted to play, is a Morrowind set maybe 10-15 years after the defeat of Dagoth Ur (and thus a little time after the Oblivion Crisis, at the beginning of the 4th era).
I imagine it to be very much similar to normal Morrowind, but it's a lot more chaotic. Especially with the Temple and House Redoran, with the former now just coming to terms with their living gods now dead, and the latter's main city becoming Kvatch 2. The few remaining Imperial outposts will be in hot water trying to keep the peace; Forts Buckmoth and Moonmoth might even become abandoned dungeons full of Daedra.
Since the crap has already hit the fan, faction quests would be about trying to get out with all their limbs intact. I imagine them full of political intrigue and desperation, as everyone maneuvers to try and make sure theirs is the one that survives at the end.
The land will be blasted and burnt, covered with the remnants of Oblivion gates, Daedra will stalk the land (even in the Ascadian Isles and the West Gash), entire cities will be destroyed or abandoned, the people are frightened as the body count shoots ever skyward...
And you? Well, you're just another outlander. No prophecy, no Devil to deal with. You're in the same boat as everybody else. Will you save the people? Destroy them? Not care at all as you step over the gasping last breaths of that Dunmer mother just to put her valuables in a sack before walking away? Or will you not bother with the people and their things at all, and just explore and hunt Daedra and the walking dead in this wild and unforgiving environment? Be sure to watch out for angry Camonna Tong and Ashlanders (who believe, and possibly rightly so, that now is the time their lands are finally purged of the mongrel dogs of the Empire, and have stepped up their hostilities considerably), not to mention the Telvanni (who are severely taxed by their battles with the Daedra during the Oblivion Crisis up until now, and not at all happy that the abolitionists won, so again they're even more antagonistic towards outlanders [whom they blame for the Oblivion Crisis in the first place... and they're not alone]).
So all-in-all, it'll still be the same Morrowind everyone knows and loves. But just much more... violent? Frightful? Ripe for the picking?
