The idea that Eberron MUST have EVERYTHING in it is one thing that turns people off of it. Cram incarnum, pact magic, shadow magic, every monster in 4 additional Monster Manuals and the Fiend Folio, ilumians, goliaths, Exalted and Vile spells, classes and feats, samurai, truename magic, ninja, scouts, dread necromancers, archivists, dragon shamans, spirit shamans, shukenja, knights, duskblades, beguilers, wu jen, swashbucklers. . .that's part of why I didn't like it. This idea is pervasive, and I've seen among my acquaintances cases of someone coming up with a wacky combination and demanding they be playable in an Eberron game because Eberron has everything it has to be out there.
