Overview
Why just add a level when you could make a new game? Total conversions went beyond modding to replace every asset—textures, models, sounds, and gameplay—creating complete games that merely borrowed an engine. Some achieved commercial quality; a few became commercial products. They represented modding’s highest ambition.
