working on a starfinder campaign right now, some ideas:

• nanomachine cult of expansion (imperialist capitalism) that seeks to consume organic life to build self-replicating factories for more nanomachines
• anprim x luddite ideology that opposes the use of FTL travel engines, nuclear fusion reactors, or dyson spheres to uphold traditional nonextractive cultural practice
• novaliberalism, the fetishization of markets, aiming to assimilate intergalactic peoples into their various marketplaces (think every bitcoin miner in a fleet of starships, with just as much social benefit as crypto provides today)
• propaganda as ideology pursued by a hyperintelligent people who use advanced manipulation tactics simply for the proof of having changed cultures (think the cia, but aliens)
