I've yet to play this game but based on my first cursory read through I'm kind of in love with it.
I've yet to grok the mechanics, something to do with pools of D20s... there are two optional forms of this to choose from or mix together. There are Traits and Skills and Edges... some talk about 'setting stakes.'
Nothing jumped out at me as being too heavy or too clever/quirky... I'm guessing the system is fairly utilitarian and 'gets out of the way' quickly.
What REALLY has me soaring though is the setting... it's so familiar yet so strange!
At first I thought I'd have to suspend a lot, too much, disbelief to run/play in the alternative reality it presents... based on obsolete science... but then I realized how much fun/bizarre stuff became possible without directly confronting me with nonsense I couldn't swallow.
As the introduction states, this isn't Steampunk... it's based on science rather than SCIENCE! Everything in here extrapolates from acceptance of 1880's scientific assumptions, but takes part in our present day. So much is different though that it's pretty much another world.
No electronics but spaceflight is common (with lots of alien life forms on other planets)... evolution can happen in a flash, as can geological changes.
A particular favorite of mine is the scientific vindication of some of the claims of Spiritualism... and the idea of creating ghosts of living beings, on purpose, for various mundane purposes. It's a pretty wild idea in a book full of wild ideas... that aren't all that wild since they are based on a real world science that once was current/modern/up to date.
It's all a bit to wrap my head around... it's not a setting I think could just be jumped into... similar to brain-twisty stuff like Eclipse Phase this game was a bit of a mindwarp as I first read it... but it's a fun one, and not depressing/scary/uncomfortable the way Eclipse Phase felt at first.
Definitely recommended for at least a read through and mine for ideas, since I can't speak for how it plays... yet.
[4 of 5 Stars!]
