Upstream 3D illustration—not the tested Classic+ 2D session. Artwork rights review incomplete.

CIVILIZATION STRATEGYBROWSER

Freeciv-web

Rewrite a civilization’s rules, not its entire engine.

Browser play / demoSource available

Play check: Externally play-tested 26 Oct 2026: solo city/production/research and guest save/restore; four turns, full match not assessed

Reuse: Source linked; check code and asset terms before remixing.

Full play status & limits

Play: Browser at creator’s site

Source match: Deployment/source-build match unknown; neither source link is verified to reproduce the tested runtime.

Remix: Pinned source; local build unverified; manual project setup and return review.

Runtime: Browser; game server required.

Quality: No catalogue quality acceptance recorded

Revival: Revival suitability unassessed; no abandonment claim

Observed official-listed Freecivweb.com Classic+ guest single-player: founded Oldenburg, completed Warriors, selected Alphabet research, saved turn 3, restored in a fresh tab and advanced to turn 4 with matching treasury and research. This is a dated four-turn feature test, not full-match acceptance or verification of the pinned upstream source.

Remix with your AI →

A first idea: After an unchanged isolated baseline and rights/security checks pass, make one beginner-interface change that labels unavailable production choices with their missing technology. Preserve game rules and test queue selection, prerequisite completion, production fallback, save and restore. This is a proposed remix, not an implemented module.

Give this brief to your own assistant. It includes the pinned source, original credit, setup, reuse terms and a first task.

Code & assets

Code: AGPL-3.0 client; GPL server
Assets: Per-asset rights review incomplete. Project code grants do not establish blanket rights for tilesets, flags, fonts, sounds, music or screenshots. Visible music listing lacks adjacent per-track notices; this is an evidence gap, not a finding of infringement. Do not redistribute a bundled remix until selected assets and notices are verified.

What you need

The pinned freeciv/freeciv-web snapshot is a general upstream source reference, not the tested server build. The server links Lexxie9952/fcw.org-server/dev; exact deployed fork commit, matching C-server revision, dependency hashes and asset provenance remain unresolved. Neither complete verified source-to-build correspondence nor a local remix build is claimed.

  1. External play was tested without an account; same-browser guest save/restore worked despite account warnings. Cross-device and long-term guest recovery remain unverified. The tested server closes sessions after 40 minutes of inactivity.
  2. A remix requires a reviewed native C game server, Python WebSocket proxy/process launcher and Java web application; it is not a standalone static HTML upload.
  3. Choose an exact source baseline and separately pin C-server/dependencies/assets. Do not assume latest dev or the catalogue upstream pin equals the live server.
  4. Review acquisition, licenses, installer privileges and sandbox admission before execution. Current dev README says Docker setup is unmaintained; no stock installer execution is authorized by this handoff.

  • The external server controls its own availability, accounts and save rules.
  • Serving a modified AGPL client requires corresponding source availability; retain component notices.
  • Tested Classic+ isometric 2D play is not the catalogue illustration of the upstream 3D renderer.
  • The live deployment is not tied to the pinned general upstream commit; exact deployed SHA is unknown.
  • A queued Granary without Pottery produced conflicting postponing/building messages, then changed to Coinage on the next turn. This observed UX issue remains unresolved.
  • No full victory, combat/diplomacy review, independent remix, self-hosting, malware clearance or per-asset clearance is claimed.

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.
