This page is a cool and well-chosen set of resources for anyone interested in d20 games.
Talen's forge is a great website chock full of free D&D Resources. They were cool enough to link to Spells and Stuff so we're returning the favor.
Metamythos.net is the home of Dan Zappone's RPG campaign set in the fascinating world of Keshyre Dan used to drive me around in his Mercury Cougar back when we were very young and very irresponsible. Nowadays, Dan holds a top secret position with a shadowy NGO and spends his spare time developing intricate fantasy worlds. He's also a neuromancer and managed to suss out enough about Campaign Cartographer to make the maps for In the Care of the Bugbear King.
ComicMonsters.com is my faithful coworker's site devoted to his favorite subject Comic Book Monsters. It is a virtual shrine to comic book monsters. His Monster Encyclopedia will be of interest to supers or horror gamers.
RPGNow is the future exclusive vendor of Cognizant Chance products. (as soon as we finish our first one). RPGNow sells PDFs for electronic delivery. This is the way to go if you ask me. The biggest limiting factor on the whole role-playing hobby is the barrier that "professional" publishing costs put on small publishers like Cognizant Chance. This is simply because a good idea that's written well ought to be enough, but it isn't because it's far more important to be able to afford spectacular art, and to be able to buy a large enough print run to offer it to distributors, who then take all the money. Don't get me wrong, the good distributors are helping the hobby and the remaining full-line gaming stores survive, but the profit margins are razor-thin for the publishers and it makes RPG publishing an expensive hobby for most of the small press.
But, out of nowhere, RPGNow has swooped into save the day! They've got a whole new business model, they don't take nearly as much off the top of per copy sale, because unlike distributors they don't have to handle warehousing and fulfillment and customer relationship management for a nation's worth of crank game-store owners. We can pass the savings on to the customer and still make more profit per book (albeit much smaller audience--FOR NOW!!). Ryan Dancey predicted that PDF publishers would be the "minor leagues" for RPGs for the next few years. I'm quite a bit more optimistic about it, especially when you consider that the "major league" RPG companies remind me more of the Devil Rays than the Yankees.
