Following are some of my favorite AD&D links. Note that all links open in a new window.
I am the chief editor and layout person for & Magazine, a free quarterly magazine dedicated to Advanced Dungeons & Dragons. In addition to the quarterly magazine we also publish a selection of related supplements and adventures.
Ok, OSR Gaming is not my site specifically, but it is the site that hosts the & Magazine forum. In addition this site hosts forums for a number of podcasts, including Roll For Initiative (RFI).
Dragonsfoot is a site devoted to 1st and 2nd Edition AD&D as well as other out-of-print FRP games. It quickly became my favorite AD&D site and consumes FAR too much of my time!
OSRIC (Old School Reference & Index Compilation) is an open source version of 1st Edition Dungeons & Dragons. This has breathed new life into a game that has been out of print for 20+ years!
