I'm a developer for an open-world tabletop RPG called Fully Automated! The goal is to create a free, open-source game that can be to solarpunk what D&D is to fantasy and Shadowrun to cyberpunk. And the first version is mostly done. It's got:
A flexible, easy-to-play system similar to a d20 game!
A massive open world!
An easy character creator along with a dozen pre-made example characters!
A high-stakes three-story campaign with over 14 hours of content!
...And a lot more!
I'm looking for more play testers, both as players and (if you're game) GMs! We've got a Discord server where we're running games on a rolling basis. The goal is to release it for free by the end of the year. I'd like to get as much feedback as possible before then, and if possible build a community around this totally free, open-source tool for making and sharing diverse solarpunk adventures!
I'm not sure that I can help with play testing but if you want any more art, I'm already working on solarpunk photobashes and releasing them CC-BY so if you need any scenes you can't find, let me know and I'll add them to the to-do list.
Photobashes are kind of digital collages with the goal of making a specific scene out of chopped-up photographs and textures, often mixing in a lot of painting.
I start with a sketch, then start scrounging up images that fit my goal. If I'm doing line art, I trace or convert each piece to lines before working with it, if I'm going for something like a render, I find relevant textures and use them to sort of clad the sketch, slowly building a scene.
I've been playing with a few styles from renders to line art comics; the level of realism tends to determine the amount of time it takes.
