Great for Dungeon masters

Bought for use on my chessex mat for dungeons and dragons. Works great. I've had maps sit on that mat drawn with these markers for months at a time and they always come off cleanly. It was recommended that you not leave red on the mats as it could stain, so I followed those instructions and haven't had any problems.

Haven't finished playing this, but it is a great campaign for people to run. A little overwhelming for those new to tabletop RPGs, but with enough GM guidance/preparation, all works out well. Great quality book, and it is nice to have all the adventure path modules in one book. I wish that they sold flip maps for all of the maps in each adventure path though. The cost would not be high as they have already drawn up the maps for this book. That doesn't affect my review of the book itself, just would be a great accessory for the more casual tabletop players.

A very useful book for the harried DND 3.0 GM.
IF you like charts for when you are stymied for an idea, this is it.  A plethora of data-packed D20 charts for NPC's,  cities, towns, encounters (a little weak there - I am waiting for the book of encounter tables from Necromancer Games)
(I am not sure if it is compatible with 3.5, though as I am just buying the new books)

This book is great and a steal at the price. Each adventure comes together with "links" to other adventures listed in the book. It's a great logistics framework that leaves almost all of the Role-Playing to the DM and players. This is how these accessories should be. Buy this if you are a player or DM alike.

Players: These encounters have some clever treasures and puzzles. Reading through this will make you a better player. Sure you may be used to killing that highwayman barbarian who wants your possessions, but did you ever check his boots for that perfect ruby worth thousands of gold pieces!? This book is overflowing with creativity from someone who sat at Gary's table.

Dungeon Masters: A great DM is one who truly understands just how much she has to learn. This book gives you idea after idea laid out in a two-page spread.

This book is one of the core 3 books of the second edition AD&D, and as such it is required material for any dungeon master and very useful reading for beginning players. In the reviews below you can read about  several good and bad things with this book, and they are summarized  below:
a) content - the book contains the necessary basics for any game -  orcs, goblins and the like. It also contains several offbeat monsters (  lammasu, giff) you could spinkle on top of your campaign if you like the  sort of thing, and, finally, it contains a few useless super-powerful  monsters that are there simply for the "wow factor" , such as the  Tarrasque, tanar'ri, and other exotica. Of course by the time you can use  those monstrosities you'll own many more volumes detailing the creatures of  the multiverse. In any case, once you are past being interested in simple  everyday kobolds, you should buy a different version of the manual or some  of the annual compendiums.
b) format - I personally have nothing against  book format. It's easier to use, it is more permanent in nature, and is  much sturdier than the 3-ring binder pages, which were last released a long  time ago and will never probably find their way into the mainstream again  in the future.
c) usability - as far as I am concerned, the book is  usable by the most of us. It could be better, but it is fine as it is, and  the information is as expansive as could be published in the book's pages.  Language is not too esoteric and the book by itself is fine reading.
Buy  it as it is required. Move on later when you want more.

If you are a Ravenloft DM, this book will make your life MUCHeasier. Everything you'll need for quick reference in your game ishere and INDEXED (Yes, they finally made it easy to find what youneed!) I love this book and it's made my life much easier. Watch for the "Fear, Horror, Maddness check" sections - they've made them a bit separated for each class so that can muck you up a bit the first go-round, but it's TONS better than those 50 odd books from separate box sets. If you were considering buying all of those "accessories" forget it - this book covers nearly everything you could even need. Players do not really need any books for Ravenloft, and if your DM has this one you can borrow it for the rare times you may need it.

As a DM I'm getting a TON of mileage out of this book. It contains 37 mini adventures based around 4 cities on the Moonsea region of Faerun.  The adventures can be linked together into a super adventure or played separately.  Perfect for when your group just wants a side quest or little tomb or something to raid outside the larger campaign. Just pop one of these settings in the middle of the woods as they're traveling and you'll have a more diverse, fleshed out world.  The cool thing is each of the mini adventures can be wiped out in just a couple short hours and of course you can alter them however you want to contain things they need or NPC's you want them to meet.  Since it's set in Moonsea I highly recommend the Sons of Gruumsh adventure for level 5 characters to run alongside this as a larger adventure since tyour PC's will be in the town of Melvaunt and adventuring in the wilds of Thar anyway.  One of the most USEABLE adventure books/regional books I have seen.  It takes a great load off the DMs back.  I just wish they made more like this...

For the price it is a very good read for a DM [game master].  The book has some references to D&D 4th edition but the majority of the information is non-system specific.

Lands of Lunacy by Lloyd Metcalf is a great setting for your dungeons and dragons games.  I have used this multiple times, especially on nights when someone cancels and I don't want to continue our normal campaign.  I just take my characters and throw them into the Chaos Void for the night, run them against a different baddy, and then let them find their way out.  Can't say enough about this book.

Love the modules presented in this book. A bit dark as far as D&D goes, but allows some moments of levity

Love the art on the back as well. Good height if you want to hide your activities as a DM/GM.
Lots of useful charts, almost all of them are spot on and good for quick references, even has summaries of some common conditions.
Made of thick, quality material. Built to last.

New to D&D, been playing 5e for only 2 months.  This book says, robgues should go first cause they're sneaky, there is this really neat thing called bag of holding. The pages pop out like when I was 3 yrs old (ok that was neat for 30 secs to be honest).  This is great if you have small children you want to play D&D, my 8 yr old plays but does not understand a lot about what we do, i say here roll this die then tell him what it means.  I though this was going to have deeper content.  Great for the table in the waiting room at a pediatric dentist office though.

Great to have while playing DnD. Got a good variety. One of my players grabs a set every game and the others use them when they need multiple dice for spells/crits. Also *super* handy for when I DM a single session with people who don't normally play the game. Glad I made the investment. Shipping was good, packaging was normal, dice were pretty good quality (no defects, etc).

I love what Wizards of the Coast have done with 5th edition. I run D&D almost weekly and can't get enough of their materials.

Extremely high quality, the book has lovely texture and heavier weight paper which gives the impression that it will hold up for years.  In opposition to previous D&D editions, this PHB contains many rules that would previously be relegated to the Dungeon Master's Guide; like travel times.  To cover all your basic needs as a player, just get this one book and you're set.  That way only the DM needs to pick up all of the books.

A very solid book of DM gaming recommendations.  It brings world building and sandbox play to the forefront and was a good price for less than $30.  Do you need this even if you are the regular DM?  Still no. If you have a previous version do you need this one?  No. There just is not enough new material.  I can't give it 5 stars,for that reason.  On the other hand, it does have pages of great optional rules that I have never seen in print before.

I have only a couple of points to make, so I will be brief.

  I really like the new layout of this MM. The information is easy to find and use. While I tend to design my own Monstrous NPCs, I've found that the inclusion of pre-designed monsters with class levels to be a minor blessing when the PCs go off the beaten path of an adventure.

  The inclusion of suggested encounters is also a nice hand to DMs that might be feeling overwhelmed by the sheer number of monsters at their disposal. The maps included in some of the entries are also quite welcome.

  My big gripe is that the book is a bit on the thin side for its price. However, you are paying for quality, not quantity. The monsters are well thought out and each fulfills their role in an encounter very well. Whereas past books gave us more monsters, I often found that I had no desire to use about half of what was presented. While this book includes fewer "OMG! He's gonna kill the whole party!" sort of monsters, it does have monsters with a lot of traction.

  This MM suits my needs quite well, and I'd suggest it to any DM that is looking for a MM which is well laid out and filled with tools to enhance your game. Who knows? By reading this MM and learning the lessons it teaches, you may even be able to design a better game for your players.
