Eclipse Phase is an RPG published by Catalyst Game Labs under the Creative Commons License. It is available for free in a QuickStart (40 pages) edition or for $15 bucks at RPGNow (400 pages) for the full package.
So, why am I posting about it? Could it be the five 5* reviews it received at RPGNow since its August release? Perhaps. I've seen fudged reviews on RPGNow, but this doesn't seem to be one of them.
Borrowing the blurb from RPGNow:
Eclipse Phase is a post-apocalyptic game of conspiracy and horror. Humanity is enhanced and improved, but also battered and bitterly divided. Technology allows the re-shaping of bodies and minds, but also creates opportunities for oppression and puts the capability for mass destruction in the hands of everyone. And other threats lurk in the devastated habitats of the Fall, dangers both familiar and alien. In this harsh setting, the players participate in a cross-faction conspiracy called Firewall that seeks to protect transhumanity from threats both internal and external. Along the way, they may find themselves hunting for prized technology in a gutted habitat falling from orbit, risking the hellish landscapes of a ruined earth, or following the trail of a terrorist through militarized stations and isolationist habitats. Players may even find themselves stepping through a Pandora Gate, a wormhole to distant stars and the alien secrets beyond.
All that and your can try the system, get your teeth into the background, and have a starter adventure for free.
Course, I already bought the damn PDF. It looked so damn purty ;)
(late edit: there appears to be a Lite version of the rules for free... no frills, white box, plain label, artless... yada yada
Beware, I think my next posting (or the one after) will be a rant. Shame too, because I like the Trolls and C&C.
