I'm not that clear on the details, but apparently the Stellar Nursery edition of Ashen Stars is the same as the Pre-pre-order edition. In any case you can check out the details here. But what is Ashen Stars? Well, it's an RPG (system: Gumshoe) of a Science Fiction bent that's been mentioned by others as inspired by Babylon 5, Firefly, and Farscape.

For an RPG that breaks the traditional scope of play in terms of timeline, and allows zooming into the microstories and back out into the macro -- look no further than Microscope.
