The Ur-Quan Masters

The Ur-Quan Masters is a 2002 open-source fangame modification, based on the action-adventure science fiction game Star Control II. The original game was released for PCs in 1992 and ported to the 3DO Interactive Multiplayer in 1994. It has been frequently mentioned among the best games of all time, with additional praise for its writing, world design, character design, and music.

After the Star Control II copyrights reverted to creators Paul Reiche III and Fred Ford, they licensed their content to their fan community under the GNU General Public License, to keep their series in the public eye. The open-source development team remade the 3DO version as a port to modern operating systems, and allowed fan-made modifications to add improvements absent in the original release. Released under the title The Ur-Quan Masters (the subtitle of the original game), the modified remake has since been downloaded nearly two million times, earning critical reception as one of the best free games available, with additional praise for a high-definition graphics fan modification.
