The open-source project Freeciv is set to arrive on Android, thanks to the efforts of one of the community members, who goes by the name of zielmicha.
Freeciv is effectively a project that looks to resurrect Sid Meier's Civilization 2, albeit not with identical design, graphics, and code (as that would likely incur the wrath of 2K's lawyers).
Instead, the community has been writing it from scratch, ironing out issues with the game, laying down new features - such as multiple rulesets to pick from - and porting the title to as many platforms as they can.
The Android version still needs some work (diplomacy isn't yet fully implemented, for instance), but it is in a playable form, and the APK can be nabbed from the developer's website [download]. The creator is planning to release the game on the Android Market once it is fully finished.
This isn't the first time Freeciv has been attempted for Android, with an earlier effort detailed in the blog Hack Casual seemingly on hold. Hopefully, the developer will be able to finish the fight on this occasion.Thanks to Justapp for the tip.
