Been browsing the online bookstores & nobody has Road of Kings with the same cover & the same retail price as on Mongoose's web-site. Several (B&N, BAM, Wal-Mart, etc) have a Hyborian Gazeteer, subtitled Road of Kings. It has a different cover (a portion of a map of Hyboria) & it's priced about $15 cheaper. Is this going to be the same product? Or a different one?
