Even though the open source remake of Caesar III is still going through a Steam Greenlight campaign, the development of the "CaesarIA" public build has been available for some time. Originally developed by Impressions Games and published by Sierra Entertainment, CaesarAI improves upon the great city management game with further fixes and additions that was not available in the original release. Today the developers have announced the release of vb1941, although I could not find any updated changelog details.
