The source code for OAX6 can now be checked out by campaign backers as defined in their perk level.
It is still early, but even at this stage, a simple game could be created! I hope some of them get to play around with it and come back with suggestions. Of course, as development continues it will become easier (ultimately providing editing tools for this) and more complex games will be able to be created.
The instructions have been posted at the OpenArthurian website
