But does it need any further support?
- Shadowrun: Anarchy => core rulebook
- Shadowrun: Chicago Chaos (Anarchy) => adventure campaign
- Shadowrun: Anarchy 2050 => 2050 setting and adventure/campaign conversion of old (1e) adventures
It's rules light enough that you can pickup any SR adventure/campaign/setting/fluff book and run it. Making something unique for it wouldn't be useful for anyone and a LOT of every edition is rehashed rulebooks/equipment guides. I think this is the best of both worlds.
If I were to run SR ever again, it would be on Foundry VTT either running SR5 or SRA in 2050.
