Games like Archean

Remember how replayable and chaotic Archean felt at its best? These games are worth a look next.

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.

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.

Code: Terraform
A frozen planet, a silent ship, and one tool: real code. Write scripts in a Python-like language to run rovers, power grids and drone fleets, then watch them work while you plan the next move. The more you terraform, the more the planet answers back. No drag and drop, no hand holding, just engineering.

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.

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.
