In the same vein, there is the Freespace source code project (https://www.hard-light.net/about/freespace https://www.hard-light.net/about/freespace) which is the continuation of Descent: FreeSpace 2 after Volition opened their source code in 2002. The original game data is not open, but there's been a lot of community effort into creating new content and updating the original content, to the point where there's even been community translations of the original voice acting. I thought about including it as a suggestion, but the modding community doesn't seem to care about licensing. The code is all properly licensed (Apache/MIT), but FAFAICT none of the content mods come with a license file, which means it's all free as in beer, not free as in speech.
