I m a huge geology nerd and a software developer. I always wanted to try building a sandbox game inspired by Sim Earth. I also was heavily inspired by the Deep Time maps of Ron Blakey.This project just got to the point where the simulator runs result in realistic planetary life histories, it s not done by any means but I think it s pretty entertaining to run through simulations and watch the planets evolve.It s in early access and totally free, maybe if I ever make the gameplay really fun and have enough content to be worth it maybe it will be a real game, but for now its just a cool planet simulator. Open to any feedback on systems in the simulation you think would be cool to include or enhance.
