It'll be a "fully voiced D&D adventure", according to PC Gamer, which also confirms we'll travel to "Candlekeep, Icewind Dale, and Revel's End, to name a few". Iconic D&D monsters including Beholders, Displacer Beasts, and of course dragons can all be seen in the trailer, rendered in blocky Minecraft goodness.

Gotta say I'm loving D&D's ongoing penetration of pop culture. Assuming Minecraft's mechanics are incorporated, I wonder how they'll affect things? Hard to guide players through a dungeon if they can dig through all the walls...
