About the Annual
Since 2007 ProFantasy has provided a monthly subscription service called the Cartographer's Annual. Each month, subscribers get a mini add-on to CC3. It might be a new drawing style, a new set of symbols, a collection of maps, or set of tools to tackle a specific drawing type. Each issue is accompanied by a detailed mapping guide that explains the techniques used, effectively providing a series of tutorials on a huge range of topics.
By subscribing to the current Annual, you get immediate access to each monthly issue of the current year - as they are released, or retro-actively, if you subscribe later in the year. You also get access to the Laboratory, where we occasionally release beta commands or previews of upcoming products for the Annual subscribers.
Previous years' volumes
After a current year's Annual is through, we release it as a full product with all twelve issues bundled into a single download or box. This version is then available both on our website and in retail stores. The subscription version is only available through our webstore.
