Storm King’s Thunder is nice because while there is a general urgency going on in the world of “giants are causing havoc” there is still time for characters to go off and do their own thing, explore new areas, and meet new people. It’s less “we need to deal with this — now!” and more “we’re going to have to deal with this as it develops.”

I just love this kind of aproach. The Pathfinder Adventures Path do that very well too.
