If you are a fan of deadly dungeon crawls, the Emerald Spire is the next edition in a long line of superdungeons. Being a fan of old-school DnD dungeons like Temple of Elemental Evil, Tomb of Horrors, and Rappan Athuk(My personal favorite) I have found this dungeon both taxing on the character as well as the player. Written by some of the gaming industries biggest authors, Emerald Spire has 16 different but similar levels, all of which have their own blend of taxing terrain and monsters. The one downfall, and biggest reason this didn't get a 5 star rating, is when the dungeon was designed it seemed as though none of the authors talked to each other in an effort to provide some type of continuity between the levels. Again though, Emerald Spire is a great dungeon and definitely worthy of my time, and I fully expect to lose more characters by the time we are finished with it.
