Kinda late, but I http://forums.nexusmods.com/index.php?/topic/1248431-moving-on/?hl=%20firebase%20%20zulu since I don't obsessively check on all the best mods since I know they take time.

I think this deserves a moment of silence. :c Now who will the New Vegas community look to for all the best quest mods?

The best quest mod for me is D.E.I.M.O.S.

The questline and detail even after the ending is great. Made by the creator of Falskaar (is that how it's called?) for Skyrim.

I liked The Inheritance though. It had some good dialogue options.
