unciv

Unciv is an open-source, moddability-focused remake of Civilization V for Android and desktop, built with LibGDX. The README frames its target audience plainly: it does not aim at high-resolution graphics, big soundtracks or animations, but at a small, fast, moddable, free and open-source 4X game that can still run on low-spec hardware. Installation is offered through many channels. On Android it is on Google Play and F-Droid. On Linux it is on itch.io, as a Flatpak on Flathub, and in the AUR. On Windows there is an MSI from the latest release, plus itch.io, Chocolatey and Scoop. Raspberry Pi users can get it through Pi-Apps, and macOS through Homebrew or a documented manual guide. Standalone jars, APKs and Windows/Linux builds are also published in Releases, with jars run via java -jar Unciv.jar; the README notes these are not recommended because releases come frequently and downloaded copies quickly go out of date. Building from scratch is documented for developers. A Docker path exists as well: with docker compose installed, building and starting the container exposes a VNC session on port 6901, and a prebuilt image is published on the GitHub container registry for the same workflow. The stated roadmap runs in a fixed order: polish first (UI and UX improvements, and better in-game automation and AI), then Gods and Kings mechanics, then Brave New World mechanics such as trade routes and a world congress. Contributions are organized by role: programmers, translators and modders each have dedicated documentation, and translation completion is tracked in a properties file in the repository. Issues and pull requests are the main route, with finished work landing in the next version; the README also suggests spreading the word by voting for the project and posting about it. The FAQ answers common questions: there are no plans for iOS, Steam has declined to host the game, features that exist in the original Civilization V will be implemented while other ideas may instead arrive through the expanding mod support rather than the base game, Civilization VI is out of scope, and tutorial material lives in-game under civilopedia with the Civ V wiki as a supplement. On legality, the README argues that game mechanics are not covered by intellectual property rights, cites US Copyright Office circular FL-108, states that reusing the original game assets is illegal, and describes using the Civilization name or impersonating the games as probably illegal. Licensing: the game is under MPL 2.0, while media files come from many authors under a mix of CC BY-SA 4.0, CC BY 3.0/4.0, CC0 and public domain, with credits listed in docs/Credits.md.
