Space Architect
Mine asteroids, build production lines, keep your crew fed and trade with passing ships to buy back your freedom.
If the replayable and relaxing rhythm of ASTERSTEAD stuck with you, this helps. These games could fill that gap nicely.
Build and run a space station where every pipe, wire and gas molecule matters. Stationeers models pressure, heat, power and farming as real systems, so survival means actually understanding what you built. Play alone or with friends, start with a cold metal box, and engineer your way to a thriving base.
Replayable, Relaxing
Planetbase puts you in charge of a small band of space settlers on a remote planet, and it is your job to keep them breathing. Build the base, grow the food, keep the power on, and turn a fragile outpost into a colony of hundreds in a place that would very much prefer you failed.
Replayable
Warm up a dead planet, melt its ice into rivers and oceans, and cover it in forests. Build truck routes, train lines and drone depots to feed three growing cities, and watch a whole world come alive. A calm, colorful logistics game where the planet itself is the puzzle.
Replayable, Relaxing
Astro Colony is a relaxed automation game in an endless procedurally generated universe. Build conveyor networks, move and dock your stations, recruit astronauts and research new tech, alone or with friends. No timers, no punishing failure: just you, a growing colony and a galaxy of voxel planets to strip for parts.
Replayable, Relaxing
Oxygen Not Included is a space-colony sim about keeping cheerful clones alive inside an asteroid. You dig tunnels, pipe oxygen and water, wire up power, and fight heat, hunger, and stress. Systems collide in clever ways, failure is funny, and a working base feels earned.
Replayable
Build a lunar colony Earth depends on. Mine regolith, run conveyor-and-drone factories above and below the surface, keep your colonists fed and sane, and trade with rival factions whose politics you can bend. A story campaign with multiple endings, or sandbox at your own pace.
Replayable, Relaxing
Sandustry is a factory game where every pixel is stuff you can mine, spill, melt, burn, or blow up. You start sifting gold from wet sand and end up plumbing steam, lava, seeds, and ice across a fully destructible planet, hunting artifacts left by an ancient civilization.
Replayable, Relaxing
Build a planet-wide industrial network from nothing: mines, farms, factories, and the trains, trucks and drones that feed them. Automation Empire is a gentle, low-pressure factory sim about untangling bottlenecks and watching your machine hum. Seven planets, one goal: efficiency.
Relaxing
Mine asteroids, build production lines, keep your crew fed and trade with passing ships to buy back your freedom. A cartoony colony and automation sim where every run plays out differently.
Replayable
A complex but not difficult voxel automation game with belts, trains, teleports, and even catapults for transport. Achieve efficiency through smart water control. Play with or without enemies. Produce materials and fuel for a spaceship. Deal with the toxic side effects. Can you Revive & Prosper?
Replayable, Relaxing
Deep Space Outpost is a space station building & survival game, involving resource and base management. Build your space station tile by tile, mine asteroids, refine materials and keep your station operational.
Replayable, Relaxing
Asteroid mining with a deadline: rocks drift through your claim, you land, set up extractors and Workerbots, and haul everything back before the asteroid leaves range. Automation grows from your own two hands, contracts pay the bills, and every credit moves you closer to a Residency Permit on Earth. Calm, replayable, and best in short sessions.
