Just finished reading this issue, and wow, i am amazed. Never really looked at Dungeon much before, but recently have started to collect them, just for ideas.
I would suggest anyone into fantasy RPG's grab this issue. I dont ever pay attention to the Polyhedron side, so this review is only for the Dungeon side.
This issue is full of little ideas to throw at players. The first adventure, The Elfwhisper, i actually did not care for, but all the other parts are pure gold imo.
The short adventure Totentanz is really easy to include into any ongoing campaign and takes a rather odd look at undead.
After that, the even shorter adventure, Prey for Tyrinth, is only a few short pages long, but can easily fit into any adventure as well.
The super adventure, Tears for Twilight Hollow is a long adventure, that in all i would not use altogether personally, but there are so many parts to it that each individual part can easily be put into other adventures. Two constructs in this adventure are a must read too ... The digging machine and the construct beholder! Pure genius IMO.
