The Planet Crafter is my greatest discovery this year. A cozy game, with no headaches and no combat. You're on your own (or with your mate) on a hostile planet and you have to create an entire ecosystem. You get to see how it evolves as you go along, a little water, then a few plants, trees, etc... and it's really nice to see the planet slowly evolve. In short, I recommend it to everyone :) https://steamcommunity.com/sharedfiles/filedetails/?id=3317074150
