This is an idea I had considered with my group before. We added some retro-futuristic aesthetics to Eclipse Phase, and altered the tone somewhat. Instead of a dark, hard scifi horror and conspiracy setting with high mortality rates for PCs, it's now a retro-futuristic ark, hard scifi horror and conspiracy setting with lower mortality rates. Why did I do this? So the PCs go from survival horror to pulp heroes. The cosmic horrors are still there, just the players can punch back a bit harder. This can significantly lessen the horror tone at times, and game balance changes a bit. There's a few ways to do this: Rules: -Boost number of times Moxie is used. -Increase points and skills at character creation (doubling is more than sufficient). Alternatively, use a different ruleset with less numbers and more action, such as Wushu. Aesthetics: -Art Deco comes back. (Perhaps a style of Neo Art Deco using modernized materials?) -Machines and manufactured items are curved, streamlined, and have fins. -Fedora hats and trenchcoats return as dominant fashion (fashion doing a full circle, essentially). -Weapons look like early 20th century firearms (Tommy Guns, Mauser C96 pistols, etc.) . I added some backstory fluff for this: Common types of tactical net weapon identification software got confused when it encountered archaic looking weapons. However, the weapons were actually modern ones that can shoot caseless ammo and have high tech parts under the hood. By the time this was corrected, the aesthetics of weapons were changed to further confuse tactical software. So, while it may look old, it's a high tech weapon in disguise, and more a choice of aesthetics than anything else. -A reason a lot of the retro stuff is common in new habitats and colonies is that some autonomist nanohackers dodged hypercorp intellectual properties by exploiting fads and items popular centuries before the Fall that had long since lapsed into public domain. Some Extropian hypercorps helped bring the fad to the Inner System. Other fun ideas: -There's a new type of swarm based morph, the Shoggy, only taking the shape of a blob instead of nanoswarm. The nano-blob is mostly made of organic molecules, isa construction/utility blob, and can form eyes and tendrils at will. It also shouts "Tekelili!" Originally made by HP Lovecraft fans. -Jovian Junta literally starts dressing like a certain infamous German regime for memetic purposes. -An Ego Hunter or mercurial uses a private detective type archetype.
