Your Favorite RPG Supplement, for any Game, Period

[Odhanan]

So, Teflon Billy was referring to that "one favorite RPG supplement, for any game, period."

What would your own best RPG supplement, the one supplement that beats every other supplements for any other RPG, ever, be?

Oo la la. Good question!

I like Polyhedron's "Omega World" mini-game - that book has had a lot of use at our table. I've used a lot of it in my own post-apoc campaign. I'm also a big fan of the d20 Call of Cthulu setting - another book that has seen use in a variety of different settings. I've run a D&D roman campaign using a lot of cthuloid gods, as well as a zombie campaign where the PCs were destroyed in the MASSES, and a hundred bazillion more. Lots of fun.

Yeah, d20 CoC would be my nomination.

I'd have a hard time limiting it to one -- and I'll leave out d20/D&D stuff for the moment so I can see a few years down the line what stands the test of time. Also leaving out modules since they often get their own thread.

From the past:

Strikeforce by Aaron Allston was a really cool Champions supplement. Lots of nice ideas in there.

Sprawl Sites for Shadowrun was really useful.

Delta Green for Call of Cthulhu -- the Greys are Fungi from Yuggoth in disguise! Brilliant!

Freedom City

Just a tour de force of setting design, production values and rank cleverness

Walks a fine line of paying homage to genre archetypes, while still managing to be fressh and exciting all on it's own.

It beat out GURPS Conan, the previous titleholder.

Right now, it is Guardians of the Forest, an Ars Magica setting book describing Germany in 1220. I really like how it blends myth with history and imagination.

Top Secret/SI had a supplement called G4 File: Guns, Gadgets, and Getaway Gear that I still use to this day for D20 Modern. It had stats on all sorts of weapons, vehicles, strange gadgets, etc.

Delta Green for Call of Cthulhu -- the Greys are Fungi from Yuggoth in disguise! Brilliant!

I see your Delta Green and raise with Delta Green: Countdown, which despite the fact that it was written for a modern day horror setting is one of the best idea mines for almost any campaign setting.

A really disturbing cult that practices self-castration? Check.
A new and cool take on the Hastur Mythos? Check.
A group that kidnaps important people and drills holes into their head - and which is actually the good guys? Check.

Really, any campaign can be improved through trepanation...

All time favorite ... ?

I would have to say Dark Space for Rolemaster, written by Monte Cook.

It had everything I was looking for in a mixed genre ( fantasy / sci-fi / horror ) setting. From bio-grafts to space pirates and from planets on the verge of reverting back to barbarism to the horrors of the Vathlacna ... that setting supplement had an incredible amount of both crunch and fluff that it made my head spin.

I've played it about a half dozen times wth different groups and each one has become enthralled by it.

Strikeforce is, without any doubt, one of the few roleplaying games I can read and re-read time and again. And I've never actually played Champions.

Call of Cthulhu d20 is similarly awesome, more for the design advice and background details than any particular love of the rules conversion.
