One idea I had a while back for a con game is a far future science fantasy portal fantasy, where the PCs keep (as in, each slot) finding themselves awaked in the Gamma World/Wizards/Dying Earth era, having been summoned forward in time using their cryo-presered bodies. Except that it is Now, and cryo-preservation isn't really a thing (they know about).
The point of the thing is that Something Is Coming in the near term from Now, and the forces bringing the PCs forward (simply because those were the cryo forms they could find) want to master their own world based on what the PCs can tell them about the Event. But the tech isn't precise and they first get the PCs before the Event happens. Now the PCs (who start out not knowing one another) know about the Event. Can they do anything in their present/the past to stop it? If not, can they escape permanently into the wild and weird sci-fantasy future?
I have details to work out of course, but what I really ned is a game system. I am kind of leaning toward the *WN games from Sine Nomine, since I could pretty easily mash them up.
