Mars Horizon
Design rockets, manage budgets and steer your space programme from first launch to the red planet.
If Buzz Aldrin's Space Program Manager left you wanting something replayable and retro, you have options. These games keep things close enough to feel familiar.
Run your own space agency from the first satellites to astronauts on Mars. Build the base, design rockets, race rival agencies, and make the calls in mission control when things go wrong. A calm, well-organised strategy game about planning, budgets and the slow climb to the red planet.

Reentry is a realistic space flight simulator that teaches you the procedures, then hands you the capsule. Power up, orbit Earth, navigate to the Moon, and feel what it was like to be the astronaut in the seat.

Run a space program staffed by small green Kerbals who smile through every crash. You build rockets from parts, fly them on real orbital physics, and try to bring everyone home from moons and planets across the Kerbol system.

EarthX is a rocket company management game. Go from launching small rockets on Earth to eventually building a colony on Mars. Create your own Internet constellation, develop new technologies, supply the International Space Station and terraform Mars!
Also in Tycoon
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.
Replayable
Build rockets, planes, cars and whole planets from parts you stretch, reshape and paint, then fly them with realistic physics. Automate flights with a visual programming language, run an aerospace company in career mode, or just tinker in the sandbox. Simple to start, deep enough to keep a space nerd busy for hundreds of hours.
