I have a few ideas based upon survey results, but nothing definite. Just so you can see the results too, they are below.
(Scores based upon: Cool =2; Good = 1; OK = 0; Nah = -1).
Fantasy: 5
Post Apocalyptic: 4 (Mad Max and Jorune both mentioned).
Futuristic: 4 (Fire Fly mentioned)
Star Wars: 3
High Seas: 3
Simply based upon those there are a few good ideas. Some people liked the idea of ships, but you could do that in a futuristic setting too - just starships. Obviously a post apocalyptic world works with futuristic stuff, but could also incorporate fantasy, such as aliens, warping energies, mutants, undead all playing a part in the apocalypse. Something like Fire Fly combines a few of these ideas.
Sundered Skies combines a few, but Necropolis 2350 would be even better. Necropolis 2350 also includes undead (the one listed common enemy that was desired) and it is military-based, which might suit Blair (the only one interested in Weird Wars.
Star Wars is an obvious choice for all of the above, being a combo of fantasy and futuristic.
I have even been brewing my own idea for a PA game based loosely upon the TV show The 100. For this I could easily incorporate ideas from other settings, and again, what exactly brought on the apocalypse could be changed.
Just for interest sake, here are the rest of the results:
Foes: 2 (Undead listed, but another mentioned having a common enemy being desirable)
Pulp: 2 (Indiana Jones mentioned)
Modern: 1 (Cthulhu & MI spy game mentioned)
Magic Level: 1 (Not much interest in varying magic level)
Weird West/Steam Punk: 0 (Kind of good, as I am about to start one of these at school, though Sundered Skies is steam punk level tech).
Weird Wars: -1 (Russia campaign mentioned. I would like to run the Russian campaign one day, but not this time ;)).
Cultural: -1 (Not a lot of interest in this front, though easy to incorporate something into any game. Native Americans the only mention).
So, I am bringing a lot of stuff, but I can't bring everything. Bringing what I can relating to the top choices.
Bad time to be bringing so much, as I have to bring a lot home, including all my matresses for GF weekend.
Anyway - feel free to give last minute thoughts :)
