Thanks. I've not read or played Chuubo, but my 1ed Nobilis is a prize possession! A wonderful achievement, and seminal, at least for my journey in the hobby. Though I'm tempted to say mechanically now it does feel a little tired (or perhaps my memory is biased, it's been quite a few years since I played it).
James Wallace (of Hogshead as was, who published Nobilis, and other really groundbreaking games like De Profundis, and his own Adventures of Baron Munchausen) has been slow-motion (i.e. mostly failing at) releasing an interesting game "Alas Vegas" via kickstarter for a few years now. Given the esteem he was held in at one point, it's a shame to see so many folks who felt burned by the kickstarter. His publishing decisions definitely helped get the hobby where it is today. Nobilis being a particularly good example.
