1: The return of the Dwarves. The story could be epic.
2: Play in all of Tamriel. (This would probably be a feature for Elder Scrolls online, which I have no interest in, nut it might be nice for a real Elder Scrolls game).
It is; elder scolls online features all of Tamriel.
But the problem with that is, for a normal ES game It'd have to come on a disc per province and it would have a development time of about 20 years for it to have any sense of consistency or immersion. Which by then everyone would be whining about the graphics. I assume ES online is going to rely on players to fill out the world.
Personally, I like to think Bethesda knows what their doing and I won't need to give any opinions.
Black marsh would probably be my choice of province.
I like the direction that they took with skyrim, I agree that a lot of things, like stats weren't nessasary in oblivion and the perk sytem was a good idea.
It allways bothered me that I could have a wisdom stat of 100, but my characters dialogue still had the vibe of a blundering idiot.
Though I hope they get rid of the "increases damage/effectiveness by 20%" perks. I don't know who thought that was a good idea, they weren't in Fallout. They arn't fun, they arn't what they were aiming for with perks. I expect that to just happen as I improve my skill-I shouldn't have to waste a perk point on it.
2 major things I would like though;
1. Go back to the Blunt/Blade skill system, it made way more sense realisim-wise and it allows greater weapon variety.
2. The return of spellmaking - a lot of being a mage is not just simply "I can cast spells!" it is the idea of experimentation, a feeling of making academic progress - not just rank progress. At the moment the only thing we can experiment with is Alchemy and Enchanting and even then its not very exciting.
