In one not-so-serious, no-holds-barred, kitchen-sick-esque world that I am creating, Dwarfs are all Psions and have a natural affinity with Crystal, which they eat like other races might candy (or a meal, depending on variety). Did I mention they are all incrediably depraved and evil? Yeah, they are

(Favoured Class: Psion)
Orcs are highly religious, psuedo-AEyptian, demon-binding necromancers of a great southern Empire. They are ruled by a divinely-chosen Priest chaste (sp?) and are LE generally. They are also the most formidable slavers in the known world. (Favoured Class: Dread Necromancer, or Summoner [Wizard Specialist UA Varient])
Halflings are dinosaur-riding savages who are ritual canibals and moon worshippers. They live in a vast plains area and have little good relations with the other goodly races. (Favoured Class: Ranger or Barbarian)
Thri-Kreen are wandering contemplatives who many ages ago had their homeland destroyed by high-magics of some long-lost empire. They seek to find their "Atlantis" on the many beaches of a great archipelago their inhabit. They trade with many folk for small items and are conpetent warrios in their own right. (Favoured Class: Scout)
Chitine are a race of reserved, greedy traders who are masters in magic and coinage. They fight dwarves for control of the underdark, seeking out gold to further their vast trading empire, and magical secrets buried underground long ago by one of the Creator Races. (Favoured Class: Wizard)
Elves are simply another anme to call "fairies".
Gnerls are beatial, 3 foot tall Gnoll-kin who have jaws which can snap as hard and fast as a crocodile's and whose mouths can stretch as far as a snake's. They live in small tribal villages, which regularily war upon other Gnearl villages, human cities, et al. (Favoured Class: Barbarian)
Toucou's are a race of sentient bird-folk similar to toucans. They are shy, but benevolent, and are well-versed in ancient lore and are very religious in their own right, worshipping a pantheon of various rain, lightning and weather deities. (Favoured Class: Archivist)
Puibo's are a race of cat-people who aredaring, aristocratic cat-folk. They are dashing swordsmen, coy speakers and always one step ahead of the game. They generally inhabit human cities, either right beside humans in "parliment" (can't think f a more fitting word for that right now) or in the undercity, in theives guilds. (Favoured Class: Duelist or Rogue).
That's about all I have for now, but hope that gives you some ideas
cheers,
