I have been discussing the next Barbarians of Lemuria project with Simon and he seemed enthused about it (so much so he even offered some of his own work that was sitting "in development").
The working title of the project is "Sulan" and is basically the BoL engine powering an Oriental/Asian flavored setting similar to that found with shows like Avatar: The Last Airbender, Kung-Fu Panda, and Jet Li and Jackie Chan's Kung-Fu fantasy film Forbidden Kingdom.
In Sulan I'm working on a world combining elements of Chinese, Punjabi, Arabic, and Southeast Asian Myth and culture. Careers have been added and Boons have been re-worked to add Wuxia flavored Martial arts. I've also been working on Chi Powers-similar to the psychic Powers found in Dicey Tales #1.
