The game engine is currently in Beta testing…..
As things stand, Paizo have asked that no copyright material be distributed as part of this plug-in.
The game engine knows how to automate the scenario setup which saves a lot of tiresome card manipulation however all the proxy cards contain only the name of the card, its type and the set it comes from. All other card text is used under the Paizo community use policy and is based on information already in the public domain (i.e. the character sheets)
Obviously you can refer to your own cards to see the full rules text, or you can scan in your cards and add the images to OCTGN. If you do this, please be aware that you can only use the images for personal use.
