More factions that are at odds with each other.
Aside from the Stormcloak/Imperial factions, it seems like too many people are getting along. It would be amazing if we could have factions with the tensions and interconnectedness of Fallout: New Vegas in an Elderscrolls game.
Additional skills and perks would be nice, but IMO not necessary. Maybe some perks that aren't skill specific.
NOOO!!! I dont want The Elder Scrols: New Vegas!!! Keep Obsidian away from TES!!!
I swear, if Obsidian make a TES Spinoff, then I am going to stay as far the f*** away from it as I possibly can.
