Which RPG company is best-represented by number of titles on your bookshelf?

We're currently moving and some stuff is packed, so that messes up my numbers a little, but right now its a tie between Palladium (mostly my Palladium Fantasy stuff and Troll Lord Games (largely thanks to C&C and the Gygaxian Fantasy line of books).  Right behind them is Paizo and GDW/Far Future (Traveller).  Then, its Wizards of the Coast (3.5 stuff and a little bit of Forgotten Realms I left out).  Eveything else is a book or two here and there.  I suspect along with TSR (which will edge out Wizards soon enough), those top spots might be about the same when the rest of my stuff is unpacked.

FASA. We have every Earthdawn book and every Shadowrun book [with the exception of some adventures, I suspect]. There's a little bit of WotC on the shelves, too, and some one-off books from other companies, but almost everything is FASA.

Hmm. I'm not much of a collector. It probably comes down to a tie between White Wolf and Chaosium, because of Mage: The Ascension and Call of Cthulhu, respectively.

WotC, followed closely by Chaosium and Black Industries.

For sheer volume, I'd have to say Star Wars (all incarnations up to SAGA) as a whole eats up tons of shelf space for me.

Second up is GURPS, followed by AD&D (the TSR stuff, that is).  My Warhammer stuff is also right up there, but it resides proudly in a completely different portion of the house.

Either D6 or Castles and Crusades.  Both have about a foot of shelf space.

Dream Pod 9, mainly Heavy Gear. Palladium and FASA stuff are next.

Kenzerco, but not for rpg's so much as for the huge stacks of KoDT comics I have.

TSR by far, especially with all those old issues of Dragon magazine taking up shelf space.

Completely forgot, but GDW has a fair share of space as well.

TSR.  OD&D, BX D&D, AD&D 1e and 2e books and modules, Gamma World 1e, Boot Hill, Metamorphosis Alpha, along with about 6 years worth of Dragon and Dungeon magazines from my high school days and a few issues of TSR-helmed S&T mags pretty much have everything else beat when it comes to shelf space.

1st) Traveller - I've got a whole shelf just for that game. I've got books from each version published.

2nd) D&D - Mainly 3.x and Basic versions, plus a bunch of Third party stuff

3rd) 2300AD - I've got a lot of it, too.

4th) Everything Else - Most of it is R. Talsorian Games products, then some GURPS.

I think Palladium actually wins out for me.  Followed closely by TSR.

Steve Jackson Games wins, no doubt.

After them, maybe Chaosium.

TSR, by far. All of teh Dragon magazines, modules, BD&D, AD&D 1e and 2e, a ton of splats from 2e (man I have a lot of stuff from a game I virtually never played), etc.

Then WotC, for all the 3.5/d20/4e stuff (yes, I have the core rules).

The SJG for Gurps basic and some additional books for 3e, and the core 4e (again, a game I've yet to actually play - but I love those rules for the sheer effort!).

And last, but not least (amidst a smattering of other stuff), and heavily influenced by Bill's generosity, Hinterwelt. I've got Roma Imperius, Shades of Earth, and several "versions" of Squirrel Attack! - like Squirrels Ahoy, Squrriels in Space, Freedom Squirrel, etc.

Oh, and I forget, I've got a bunch of old ICE stuff for Middle Earth stuff. I used to love buying that stuff and just reading how they interpreted the source material.
