One thing i'd like to see is if you shoot a deer or another animal with an arrow and simply wound it, i'd like to be able to follow it and have it bleed out instead of running around with an arrow in it's face.
Better combat as well, i've been playing Demons souls allot lately and going back to skyrim... the fighting seems so airy, like when you hit something, you just hit a hollowgram. as well i like the parring in demons souls and the roles, they add a certain... weight to the game, i'd love to see that in Skyrim.
I WANT GUARDS TO BE USEFUL like they were in old games, give you directions, give you the latest rumors not just simply lame one liners.
Inns... don't get me started. I want an inn, not a funeral reception, no wait, funeral receptions are more lively then the inn's in skyrim. that's what i want most, loudy laughing, fights, drunks. the works!
Your ideas?
