Things are happening differently over at Wizards towers. The tide of source-books which characterized 3E and 4E has been stemmed. Latest in its new line of story-driven mega-adventures, Princes of the Apocalypse is a hardback adventure module featuring exploration, investigation, and a whole lot of dungeon crawling.
Advanced word on this one was very good, so I expected to be impressed. For £30 or thereabouts, it didn't disappoint. Quality is evident inside and out: 250+ pages of terrific art, cartography, and writing. There's a hundred or more hours of role-playing in this thing, and that makes it great value.
