A first idea: Study a small Lua mission or interface component, checking all notices. A personal fork is not automatically eligible for upstream submission: Pioneer rejects materially AI-generated contributions.

Source, setup & reuse terms

Open-ended single-player space flight, trading and combat simulation with planetary landings, missions and a procedurally generated galaxy. Official 7 September 2026 development release adds atmospheric lighting, thruster plumes, landing aids and smuggler holds. Features are upstream descriptions, not local playtest results.

Code & assets

Code: GPL-3.0 core code and extension modules; third-party libraries retain their notices
Assets: Art/music/assets generally CC BY-SA 3.0; AUTHORS.txt retains font, NASA/public-domain and other component notices

Original licence notices ↗ · Asset notices ↗

What you need

Official main source includes runtime data; separate asset-source repository linked. No immutable release-to-source correspondence or local build verified.

  1. Use an official Windows or Linux development build; no Game Commons browser runtime is provided.
  2. For source modification follow COMPILING.txt and preserve AUTHORS.txt component credits. Upstream does not accept materially AI-generated contributions.

Official source linked; immutable revision and release/source match not verified.

Official September 2026 release, source README and asset notices reviewed 26 October 2026. No game installation, local build or playtest performed. Official image is not our playtest.

  • Not locally downloaded as a game, installed or played; no malware clearance.
  • Do not promise AI-generated share-back acceptance: upstream README explicitly rejects materially AI-generated code, comments and design suggestions.
  • Keep individual asset/font/NASA notices; source availability does not prove every asset has one uniform licence.

Saved GitHub information.

Repository activity is separate from the reviewed source version. GitHub’s licence detection does not clear artwork rights.

About these listings

Listing, price and licence information is upstream-reported, not our gameplay testing or remix permission. Recommended prioritizes reviewed picks, then source-reported released games with free access, imagery and strong player-rating evidence. These are discovery signals, not our gameplay quality score. Most rated uses sourced rating/review counts, not players. Device and engine filters reflect source reports; Godot is an engine, not a platform or quality certification. Unknown counts rank last. Price reports do not establish original-content rights or working gameplay. Curated source foundations are additional project guides; main search includes their matching entries. The listing count does not silently add or double-count those guides.
