I've already sent an email to Bethesda about this. Let's hope game developers will look here for inspiration!

ok! this is what I want in Skyrim!
When the character rolls, falls on the ground, earth, dirt his skin/clothes should get dirty. Same thing when swimming or raining ( wetlook). There will be a lot of snow in the new game how about making snow stay on the character. Also wounding effects... skin should get bruises/cuts/bloody wounds.
I bet this will add a lot of immersion to the game! let s hope their tehnology allows them to do this, if not lets hope they will buy or develop it

What are your ideas!?

I not know!

Control undead (like turn undead)
Dismiss summoning (effective against your own and enemy's)
Greater skill buff for conjure weapon
Ability to absorb trapped souls into your own mana pool
Mind affecting spells
Better reanimate (turns dead npc to perma-slaves untill killed)

I don't know how to make something better which isn't even released yet, we know a lot about this game now and yet we know so little.

Making skyrim better is something that that modder should do after we know this game thoroughly.
