5 out of 5 rating for D&D 5th Edition Dungeon Master's Guide
If this seems like a glowing review, well...yeah. I like the other two core 5E books, and my gaming group is collectively pretty excited about the edition too. But I love this book. There's just so much here, so many tools to use, levers to pull, switches to flip. At the same time it manages to accomplish something D&D desperately needs — it teaches you how to be a DM.
