I'm curious if Fully Automated might sort of qualify for the collaborative fiction bit - the manual and initial lore was written by a small group of devs, GMs, and players with all three groups picking up members as it went on. I joined as a spectator, to have a place to talk worldbuilding, then started making lore suggestions that got incorporated until they eventually made me a dev. We added one more the same way in the last year.

Much of the original worldbuilding was focused around the southern California area, but so far pretty much every GM who's joined and ran a game just grabbed the parts of the setting they liked and wrote the solarpunk future version of wherever they live. (I certainly did when I wrote my campaign!) I think the narrow focus is a strength of the original manual - it makes zero effort to dictate how most of the world looks and invites the reader to write it in.

There's no enforced cannon, the dev team really doesn't want that kind of control, preferring to provide lots of options and modules people can pull from.

The devs work to support new GMs and writers who want to pick the world up and make their own area, including giving them their own channels in the discord. The long term goal is to publish campaigns, adventure modules, even loose factions, geographic areas, bits of lore, gameplay mechanics etc when people contribute them. In this way we're trying to cede control of the thing basically right from the start.

So far there's only a couple bits of prose fiction in the works, and one of them is the gamebook I'm working on, but I don't see any reason we couldn't do more of it or that the community wouldn't be thrilled to have it.

Also it's not collaborative fiction, but we do have a place to share solarpunk worldbuilding research: https://wiki.slrpnk.net/writing:start

The New Wilderness by Diane Cook

added to my TBR. Thanks!

The Mongoliad

Very interesting. It seems to be a reoccurring theme that all these project took place between 2005 and 2015

You are right. Without any guide rails and moderation, such a project will most likely fail. But how is the vision of the whole work established? It can't be the conductor telling people what the vision is, because in that case it would be easier if the conductor wrote the novel along. Maybe the focus of the work could be established by something like the snowlake method by Randy Ingermanson? In the first phase, people come together to create the core of the novel, in the next, more details of the plot are determined. In every phase everybody can contribute, but a latter phase may not change what an earlier phase said the novel is about.

This would enable a much richer experience just like an orchestra with different instruments and voices.

Solarpunk, historias ecológicas e fantásticas em um mundo sustentável

This sound very interesting! It in fact an anthology with nine authors. And there is an english translation!

Fully Automated Solarpunk RPG

I mean, it definitely is collaborative. I think part of me wonders if such a thing would work as a written format.

Orion’s Arm

I'll look into it. A collaborative solarpunk novel would definitely need world building. Thanks for your ideas!
