Storm King's Thunder , the newest D&D adventure, is now available to play on Roll20. Reviews have been glowing and sparkling thus far. Moreover, I really feel like this is something Roll20 users have been asking for since the very beginning... a huge module that has everything. There's 200+ statted tokens, forty maps, and more hyperlinked cross-references than you can shake a Flying Sword at. James Introcaso and Kristin Carlson did a whole hell of a lot of work in Roll20 so you, the Dungeon Master, don't have to. There are months of gameplay available in this item, and it's modular in a way that you'll be remixing and rerunning it in completely different ways beyond that. And while we haven't gotten to play it all yet (again... months of gameplay), the Roll20 team finds this to be the King Lear of D&D stories, and thinks that the crew at Wizards of the Coast really knocked it out of the park. So get out there are mix it up with some giants.
