Games like Kerbal Space Program

Loved how replayable and chaotic Kerbal Space Program can get? You might settle into these games easily.

Spaceflight Simulator
Build rockets from real-world parts, launch them, and find out the hard way why landing is the tricky part. A 2D space sandbox with honest physics, the whole Solar System to reach, and no punishment for exploding. Trial, error, one more rocket.

Juno: New Origins
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.

SimpleRockets
I am excited to release my first game on Steam! SimpleRockets was released in 2013 for mobile and I've put a ton of work into it to get it ready for PC and Mac. It was inspired by KSP, and it offers a simpler 2D experience for building rockets and exploring space with realistic orbital mechanics.

Approximately Up
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.

Space Engineers
Build working ships, stations and planetary bases block by block, then fly them, crash them, mine with them and blow pieces off them. Real mass, power, oxygen and gravity keep every design honest. Best with friends and a tolerance for learning things the hard way.

Children of a Dead Earth
A space war game where the physics is the star. Design ships from real rocket equations, plan orbits with NASA-grade math, then watch railguns and lasers settle it at thousands of kilometres per second. Hard, honest, and unlike anything else: if you ever wondered what space combat would actually be like, this is your answer.

Flight Of Nova
A flight simulator built on real orbital physics, set in the Noren star system. You fly shuttles and freighters from planet surface to orbit and back, hauling cargo, docking with stations and chasing drifting containers, all by hand. It is slow, precise and demanding, and when a landing finally goes right, it feels earned.

Reentry - A Space Flight Simulator
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.
