Your best and worst book picks

[Eternalknight]

Two questions really:

Which book that you have bought, besides core rulebooks, do you get the most use out of?

and

Which book, besides core rulebooks, do you get the least use out of?

For me, the answer to the first question is Unearthed Arcana, and the second, is Stronghold Builder's Guide. Not neccessarily because it is a bad book, just that my players have never wanted to use it, and I have never needed to.

Any publisher.

 

[Kid Socrates]

Most used: Warcraft d20, Magic & Mayhem. I don't run a Warcraft game but there are so many fun spells in here I can use elsewhere.
Least used: Eberron, Five Nations. No bad reason, just haven't played in Eberron since getting this as a gift. Of books I bought, probably Warcraft: Shadows and Light, because what I thought was a religion & planar book was instead mostly a "Here are the stats for the Titans!" book. Gar. The little planar stuff in there is cool, though.

 

[jdrakeh]

Most: The Apocalypse Stone (though, admittedly, I haven't once used it as intended).

Least: Canting Crew (read it once, never even opened it again).

 

[demiurge1138]

Most used: Eberron Campaign Setting
Least used: Book of Fiends (Green Ronin Press)

Demiurge out.

 

[Shade]

Most Used: Fiend Folio
Never Used: Lords of Darkness

 

[(Psi)SeveredHead]

Most used (other than core): Adventures. You can reuse them with different groups

(If you're allowed to other books that are core for other series, then it would be D20 Modern, of course.)

Least used: D20 Future. We found the spaceship combat rules useful (with the unofficial errata). The rest couldn't be used.
