Perfect mix of the old school sensibility of the first few editions and the simplicity of v4.

Excellent way to beat the COVID-19 pandemic blues... online D&D with your buddies!

Definitely glad I read it before my first DM session. I feel like I was better prepared & able to come up with more solutions when changes happened to the original storyline I came up with.

So helpful! I feel like I’m getting a good grasp of this dungeon masters stuff! :)

I said I've finished this, but let's be real: you're never really finished with the DM guide. That said, lots of good and helpful information in here. I'm using it once a week and I still feel like I've just scratched the surface of D&D lore/rules/options/etc.

A long and tedious at times read. Recommended only to those new to being a GM or those who're looking for some inspiration in a new campaign. Contains lots of information about world building and minuscule details that might become useful (magic artifacts, treasure, dungeon building etc.), but some of the information is sometimes repeated which makes it even a harder read. I'd advise using it as a guide and a helping hand, but not try to read it cover-to-cover like I have as it might become too difficult at some point.

Continuing my D&D-related education. Helpful information and also a good attitude that gives permission to disregard, improvise, etc.

Certainly useful if you do not have any dungeon master's guides on hand, but I would argue that it is not worth the price of admission. I have my copy of the 3.5e dungeon master's guide, and this book does not have any meaningful information that the prior did not also have.

Sure tables and rolls are slightly different, and the new feats rules are a change, but I feel the real substantive changes from the ruleset are best summarized in the player's handbook. So if you are trying to go from 3.5 e to 5e, get the player's handbook but skip the dungeon master's guide until you really find yourself into a pickle that the tools on hand cannot help you with.
