OpenAlchemist is available in Fedora. It has a few bugs. I’ve fixed up the bugs and ported it to SDL2 instead of ClanLib. The original authors are not maintaining the project anymore. Should Fedora have my version in addition to the original or replace the original? My version has an alternate skin called AlchemyQuest as well.
I would say that if the original upstream is dead, you should just replace the original with your maintained version.
