A suggestion of mine concerning armor and weapon 'progression' (yuck)
Yep, I hate the term progression as to me it stems from the MMO-crowds where everything is a race to get the best gear when you level up.
Seeing that this game focuses solely on the player in a living breathing world, the game should remain in a believable state. One thing to accomplish a small portion of that belief is in my opinion the use of realistic armor availability.
With this 'realistic armor' I mean that a Nord armorsmith/weaponsmith shouldn't all of a sudden be selling Dwemer armor or Glass weapons simply because the player passed the level-up marker. Instead he should be selling a variety of different (localized) armor styles like Nordic Fur/Leather/Iron/Steel with varying degrees of protection. So he could have some chainmail with leathers and fur, but also a much heavier (and more expensive) version with steel plating and studded leather straps.
Same with the weapons really. Don't have every brigand and his pet monkey prance around with Glass Claymores just because the player is level 15. Keep them in their filthy leathers and rusty swords and have these rare and valuable weapons and armors hidden around the gameworld in ancient shrines or on powerful warlords (who need not be hostile). You want the good stuff? You have to work for it. And by work I don't mean doing a few quest for gold and pick up your Ebony Longsword at the local merchant.
This way the world will retain its sense of being realistic (in fantasy terms ofcourse) with lots of variety among the common weaponry and armor; while the rare armors and weapons will actually be rare.
So switching the design from a single Fur-Leather-Chainmail-Mithril-Glass into a design that has 5+ different versions of Fur-Leather-Chainmail in varying levels of protective values (each with its own benefits and penalties when worn) with the rare Mithril/Glass/Dwemer/Ebony/Daedric actually being rare and hard to find (but they are out there, and not part of some levelled list). I'd love to see them get treated more like artifacts and rare treasures than simple 'player-level progression tables'.
Sorry for the lengthy essay, but I just kept on typing because I'd hate to see shopkeepers to suddenly sell Glass/Dwemer/Ebony/Daedric in a town of Nords with Nordic weapons and armor. I want to find rare pieces of Daedric out in the wilds in ancient shrines and crypts; I want to collect Glass shards and forge them into a set of Glass armor etc.
So please make Skyrim into a form of 'persistent world' where the focus is on the gameworld and not an 'inconsistent world' where the focus is on the player's level.
Also, please look at this http://www.youtube.com/watch?v=4d7M9lwCDZw as I loved the depth and variety of seeing several different looking Old/Rusty/Fine/Pristine Nordic Longswords instead of the generic 'Nordic Longsword' (the only production line model available for the entire continent).
