Best Total Conversion Mods That Became Free Standalone Games

Mods for games are almost essential to the video game ecosystem. They keep interesting older games alive much longer than they would otherwise, offer players more options in how they play, and encourage would-be game makers to become modders or even developers themselves. While some mods fix broken mechanics or add quality-of-life features, others add new quests and storylines, and some mods even alter the genre of the game itself.
