Mongoose Publishing has announced that it will ship a $99.95 RPG sourcebook in August, Dr. Blottenberger's Grand Bestiary of Extraordinary Creatures.  The hardcover tome will run 1000 8-1/4' x 10-5/8' b/w pages.  The conceit is of a botanist's journals and scientific papers, which record fantasy creatures in a reference guide.  

 

The first $99.95 RPG product was one year earlier, in August 2004 -- Alderac's World's Largest Dungeon (see 'The Biggest RPG Product in History').
