Man, Steam is making it easier than ever to get back into an Elder Scrolls game now that re installing and getting any mod you want are both one button press worth of work.
That said, if anyone else has gone back to this, of the (literally) hundreds of mods I added since last playing, the two that stand out the most as worth having are
More Travelers and
Live Another Life For any play throughs where you don't care a lick about the story.
Hightlights so far include spawning from "left for dead" and almost immediately being attacked by the scavenger going through the battle sight I awoke in, and deciding not to free a Talos Worshiper because of past experiences with ass handings. Only to start to leave and hear a volley of arrows taking out two of the three guards, followed by a rush of six to eight Stormcloaks obliterating the last.
