I've added the three newest Worldbook splatbooks to the main page:

• Terafie (Horror frozen dieselpunk)
• Goslayers (starfaring humans killed Cthulhu)
• The Shrouded Globe (my own take on World of Darkness-style urban gothic)

Next upcoming worldbooks will be:

• Curse of the Djinn (Monkey Paw wishes everywhere)
• Overland (Aka "Wide Wide West." Turns out Lewis And Clark were Wrong)
• Blood Pirates of Orb (Steampunk sky pirates)

I'm also floating the idea of possibly doing expanded 50-page traditional (or half-legal-page) sized worldbooks with included system-agnostic rules for use with other systems, so if this is something you'd be interested in, please let me know!
