I'm a fan of the setting. I can't think of another game set in the Islamic Golden Age, baring Tales of the Arabian Nights, which is a boardgame anyway.
Is it just me or do I see a lot of your later games in this (or the other way around). The Jinn make me think of AW's Fronts. The Stats (more than the Skills) make me think of Poison'd's derived stats.
The whole scene of mystics vs Jinn reappears, with a different expression, in Dogs in the Vineyard.
The business of accumulating and spending bonuses is very much like Xs in Poison'd, too.
The idea that you have to provoke a Jinn, making it stronger and stronger, until it finally manifests, so that it's vulnerable to you at its strongest, is philosophically consistent with my game design since, even if it hasn't precisely reappeared.
