What other books do you use in d20 Modern?

[wolfen fenrison]

I personally love using certain books with my Modern games so much I consider them part of d20 Modern collection.
The ones I use the most (and I almost think they shouldn't count as not d20 Modern):
Modern Player's Companion
Future Player's Companion
Martial Arts Mayhem
Ultramodern Firearms
The ones I use from other systems:
Unearthed Arcana (great for any d20 game)
Players Handbook (spells only)
Psionics Handbook (feats and powers only)
Monster Manual
Expedition to Castle Ravenloft (when used with d20 Modern I call it "Castlevania d20")
Call of Cthulhu d20 (the precursor to d20 Modern and a natural fit with Dark*Matter or Shadow Chasers)
Monte Cook's World of Darkness (this book actually gains more from the Modern books instead of the other way around, but the feats in this book are great additions to whats available in Modern)

I really don't like the magic system in D20 Modern so I use the Sorceress base class from Red Star and rename it the Weaver.

Characters have to start off as a Weaver at 1st level. I don't allow multiclassing into it as the multiclassing rules dictate. Instead a character that wishes to gain Weaver levels after gaining levels in the other Hero classes needs to have 4 Ranks in Knowledge (Arcana) & Spellcraft and need to have the Arcane Adept feat (this is a modified version of the Force Adept feat found in Star Wars Saga).

Depending upon the game, I use:

1) Almost anything from WotC- Anthro Animals from Savage Species make fine mutants, for instance.

2) Green Ronin's Modern Magic and Psychic's Handbook.

3) Weaponry from Ultramodern Firearms D20

4) Second World

5) I'll lift freely from Spycraft, Star Wars, Dragonstar, and CoC D20, as needed.
