Ah, if that's all you wanted:
From the few that are there, Alternate Start: Live Another Life is the only "must have" IMO. It is a GREAT mod and makes every new game feel fresher, and doesn't lock you into doing even a tiny part of the main quest if you don't ant.
Of the rest, my only other recommendation is The Paarthurnax Dilemma. Makes the Paarthurnax quest so much better.
Open Cities MIGHT be good, but I had performance issues on PC, so I'm not sure how the consoles handle it. My PC is a bit out of date though.
Cool, I was also thinking of the Lore-based load screens one and the Level-up messages...I like the feel of them. What does the Paarthurnax one add to the quest? Background and lore or does it add things to do in the quest?
