Greetings:
We posted an article on the History & Design of the Adventure System. For those of you afflicted with the game-design bug, it is here if you are interested: http://adventure-system.com/history-design.
If you would like to contribute an article (system agnostic) on gamemastering, world building or roleplaying, please contact me directly at Scribe@adventure-system.com.
Enjoy!
