A voxel universe where you mine, craft and command your own fleet, alone or with friends on a server.
Miss the chaotic and replayable pull of Space Engineers? These games make natural next picks for you. You can bring friends along for most of these.
A space sandbox survival adventure: start in a crashed pod on an alien planet, mine, craft and build your way up to capital ships, planetary bases and space stations, then warp off to explore a whole galaxy. Play alone or with friends, and expect things to go gloriously wrong along the way.

A voxel sandbox in space where every ship, station and turret is built block by block, then flown into battle. Mine asteroids, run factories, trade, and network the galaxy with warp gates. The universe is procedurally generated and nearly endless, and it bends to your settings. Best with friends on a server.

Starbase is a hybrid voxel/vertex-based space MMO with a fully destructible and infinitely expanding universe, with a focus on building and designing spaceships and stations, exploration, resource gathering, crafting, trading, and combat.
Chaotic, Replayable
Bolt together a spaceship from thousands of parts, wire up its systems, then fly it in first person to 15 strange planets. Solo or with up to four friends, every mission asks something new of your ship, and every mistake becomes a story. Build it, launch it, and find out what happens.

Archean is a first-person engineering sandbox where physics does the judging. You gather ore, craft parts, bolt together planes and rockets, wire their power and fluids, then program them in XenonCode. Planets are full-sized, orbits are real, and if it flies, it is because you built something that flies.

Crash-land on a planet, mine and craft your way back to orbit, then build the starship of your dreams and take it into a dangerous galaxy. The building system lets you stretch, shape and wire anything from fighters to capital ships, and the whole thing is yours to fly.

Take control of a fully destructible spaceship and explore, blast or trade your way through the cosmos, alone or with friends. Every tile matters, as you dogfight, maneuver or speed your way past friendly traders, hostile aliens, and impressive space navies. What will you do, Captain?
Also in Co-op · Chaotic, Replayable
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.

SpaceCraft is an online galaxy where you mine planets, build your own ships from parts, automate bases and trade with other players. Fly out, scan a system, land, dig something up and turn it into a business. A calm, open-ended space sandbox that rewards patience and works best with friends.
Also in Co-op
Design starships piece by piece, staff them with crews of individually simulated people, and send them into physics-driven battles where every module can be blown off the hull. Explore a procedurally generated galaxy alone or with friends, test your designs in online PvP, or build without limits in Creative Mode.
Also in Co-op · Replayable
Mine asteroids, salvage space debris, design your own small or massive spacecraft using individual functional components, complete missions, and engage in battles against enemies in a vast galaxy with realistic physics based on orbital mechanics or in a classic physics mode.
