Games like Rocket Science

Miss the replayable and chaotic pull of Rocket Science? These games make natural next picks for you.

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.

Kerbal Space Program
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.

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.

Keplerian Space Discovery
Travel through the solar system in your own spaceship! The motion of each celestial body is accurately reproduced by the Kepler equation.

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.

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.

Solar Expanse - Space Exploration Manager
Run a 21st century space company: plan real orbital transfers, sling rockets past planets, mine the asteroid belt and drop water ice onto Mars. A slow, numbers-first logistics sim where a good plan pays off centuries later, and terraforming a whole planet is just the next item on the list.

SpaceEngine
A 1:1 scale simulator of the entire Universe, built on real astronomy. Fly from Earth's surface to a black hole billions of light-years away without a single loading screen, land on procedurally generated worlds, and speed up time to watch a thousand moons tick through their orbits. No objectives, no fail states: just you, the stars, and a lot of quiet.
