I've run my Eclipse Phase campaign for four years now and it's time that it comes to an end. They've been to every planetary region in the solar system (yes, including Earth) and several exoplanets. They've dealt with TITANS, super AGIs that weren't TITANS, Iktomi, the Factors, and all manner of factions , cults, and what-have-you from transhumanity.
As conclusions go it is perhaps unsurprising to see that the major forces are converging; an escaped TITAN from Earth that wants to steal the sun, the Factors are angry with the Proxies (each PC is a Proxy, with their own Sentinel team), Firewall is suspicious and worried, the Surya are staring at them with particle cannons, they've just blown up Mercury, the TITANS have broken the Interdict, and the neo-synergists - now infected with Watts-MacLeod - want them to join their cosmic thought bubble.
The problem is, everything is potentially bad news, because that's the conspiracy rule of Eclipse Phase. The Watts-MacLeod may turn out to be a Factor plant. The TITAN, now turned to negotiation, might be engaging in a cunning ruse. The rest of transhumanity will turn out to be using the PCs for their own agenda.
For those who have finished a campaign, how did you do it? Did it have a happy ending? :) Or were the characters smeared across the surface of Sol and the remnants of transhumanity with them?
