Here's a little podcast released by the wonderful folks at PulpGamer.com that lets me and a couple other gamers geek out about Oz.
If you're checking out the blog in response to that podcast, here are a few items of interest:
First of all, over on the right you'll find links to all of the places you can purchase Adventures in Oz: Fantasy Roleplaying Beyond the Yellow Brick Road. RPGNow and DrivethruRPG also offer AiO in print via their POD service.
This blog entry contains links to reviews of Adventures in Oz, and this one is a FAQ about the game that I compiled some time ago. If you come up with new questions for me to answer, feel free to ask by commenting on this post, that post, or via email at firstname.lastname@example.org
If you want some idea of the variety in the Oz stories, and the simple flexibility that the AiO system provides, check out the Oz characters and magic items that I've written up for the blog.
Finally, I do have an actual website over at www.adventuresinoz-rpg.com that has printable Oz maps and character sheets for your downloading and printing pleasure.
