Out of curiousity: for those familiar with Nobilis, what are your feelings on how deeply the mechanics intertwine with the underlying game and its target play?
I recall when reading Nobilis 2e, the GWB, that I'd felt the mechanics did a pretty solid job at capturing the cold majesty and sweeping grandeur of the Nobles... until I played, and realized that was the impression from the (ever-impressive) prose and nano-fiction provided by the author, rather than the mechanics themselves. The games tended to go gonzo. 3e softened up the impression in prose, but the mechanics remained, IMO, pretty inclined to going gonzo. And then Chuubo's came out, which continued softening the prose impression. I can't comment on the mechanics, as I haven't played it yet, but aside from stronger pacing mechanics it looks like it's still mostly Nobilis.
I'm still not sure that the mechanics actually push for Gonzo play, so much as the incredible flexibility of the powers (and resultant conflicts) pushes for it, and nothing in the game constrains that trend.
What drives these thoughts is my questioning whether the really appealing part of Nobilis - the setting, the power scale, the resultant questions that emerge in play - are actually tied into the game itself, or whether these things can be ripped wholesale away from the Nobilis engine without loss, and stitched onto the bones of a system that better drives play.
