4 out of 5 rating for Scourge of the Sword Coast
Ran this as an introduction to a sandbox campaign. It's got a lot going for it, in terms of open ended-ness and good ole dungeon crawling. However, I absolutely don't recommend using Dead in Thay as the follow-up adventure: you're much better off making other plans for bloodgate keep, or else replacing its role in the adventure with something else entirely.
