Name your favorite D&D book

[MonsterMash]

There isn't one.

There are THREE.

The Three Little Books I got back in 1975, the books that allowed me to get away from miniatures-based games and into a far, far better hobby.

...you never forget your first...

Thank you Arneson & Gygax!

Amen to that.

Apart from OD&D it'd have to be City State of the Invincible Overlord

 

[TroyXavier]

3.5 Draconomicon but there are many good choices.

1e DMG

I still read it just for pleasure.

I agree. I just bought another copy from a used book store just to read it for pleasure. It provided literally countless hours of entertainment for me over the years.

Second place would go to the 3.0 PHB, for revitalizing the game for me.

Third place would go to Monte Cook's Aracana Unearthed, for doing the same for 3.0 D&D that the 3.0 PHB did for all D&D that came before it.

I don't have many books, and all are 3rd edition, but:

for the crunch the PHB (preferring 3.0)
for the fluff Manual of the Planes

i may have to change my schtick. OD&D, you never forget your first, (1974)

 

[GlassJaw]

1ed PHB - one look at it in my cousin's basement 16 years ago and I was hooked

2ed Greyhawk From the Ashes, City of Greyhawk, City of Splendors - some of the best boxed sets ever made.
I also have to mention Volo's Guide to Waterdeep and the Dalelands as well.

3.0 PHB - even though I play 3.5 now, the 3.0 PHB got me back into D&D after many years.

GAZ 10 - The Orcs of Thar

Oh wow! I forgot about this. Now I have to take a look at it again when I get home.

 

[mhacdebhandia]

Planescape's Faces of Evil: The Fiends. From my favourite Second Edition line comes a great, flavourful resource for fiendish psychology and culture.

In Third Edition, probably the Expanded Psionics Handbook, for single-handedly making me interested in psionics - which I had always spurned before - by being interesting, well-designed, and exceedingly easy to fit into the larger context of the D&D game.

 

[el-remmen]

No surprise. . .

 

[Trance Fiend]

For 3rd Edition, I'd say The Monsternomicon.

For AD&D, Ruins of Undermountain 1 & 2. My players enjoyed those boxsets alot.
