Hmm. I sense possible uses for the Enlightened, specifically when scavenging they can find crates of chemicals that only they and a government remnants faction could make proper use of - In the Enlightened's case they can use some of them and wood to make plastics in the form of bakelite and phenolic "blocks" (actually boulders) that they can use to make some tools (like furniture for firearms/crossbows, book bindings, and circuitry,) or for building - for example, the Enlightened can use it to build computers that can access the remains of the data cloud and pull of schematics for new workshops from it given some time (like say, a 3D printer that uses Bakelite to make batches of stuff, while a Gov-Rem one would use whatever normal plastics are found or can use the same chemical batches to make a more limited amount of regular plastic,) while the Government Remnants can use it to reacquire stuff of thier own, such as plans for more powerful weapons or cybernetics (military cyberdogs anyone?)
Also maybe give them an ability to take logs and process them, potentially giving them a much more eco friendly resource in the form of a small number of different farmable seeds, as well as improving the value of the wood into smooth wood - having stripped off the bark and any branches where the seeds might have been, with the grown "crop" of Young (whatever) trees being processed into 1-3 smooth wooden logs.
And with that in mind, Scavvers would also have the means to process the wood, but not farm trees (essentially they don't get seeds from thier version of the reaction, as they don't know how to actually tend to tree farms,) allowing them to improve the value of some of thier stuff.
Ideas I had in all for Enlightened
* Bakelite and Phenolic "Blocks"
* Chemical supply scavenging.
* Possibly include a means they can sustainably manufacture chemicals for making Bakelite. Maybe certain underground creatures can be milked for a substance toxic to humans, but useful in synthesis of man-made substances?
* Data Mining via a special remote terminal building only shared with one other faction for "Eco-Tech"
* Eco-Tech includes 3D printer that only makes use of Bakelite, and if we could make some buildings require power, green-energy powered versions of their Tree Stripper, an Auto-loom to batch produce cloth with only one worker and no smoke-belching generators, an Auto-lathe to bulk manufacture ammunition for bows, crossbows, and the "Micro Ballista," as well as the Micro-Ballista itself, being essentially a man-portable siege engine that fires heavy wood or metal rods hard enough to injure someone in iron armor, and Eco-Batteries, essentially a version of battery charged via a charging station hooked up to wind turbines or water wheels that can be used in any reactions needed a battery.
And for a Government Remnants, I came up with
* Having harder hitting versions of common weapons, based on pre-disaster experimental schematics.
* 3D printers that make use of regular plastics.
* Ability to use scavenged chemicals by themselves to create regular plastic, and an inability to synthesize bakelite (as the ability to do so is something the Enlightened rediscovered independently, and makes the underground less attractive to the Government.)
* Cybernetics, their most advanced stuff, allowing the production of Cyberhounds from dogs for use in combat and possibly using dogs (or more, thier brains) to make automated turrets - think the K9000 but as a turret. Also possible use in restoring lost limbs and nerve damage as well as specialized applications such as removing the need to breath and blood filters (making someone immune to syndromes, just as an example.)
* Would need DF Hack, but endgame armor would be a type of Exoskeleton suit that greatly increases strength of the user - useful for both industrial and military purposes, as the exo suit would be great for anyone who uses heavy materials and make melee fighters much deadlier.
