Cognitive Dissonance is a fan game set in the universe of the EarthBound series (also known as Mother). It takes place between the first and second games in the series: after Giegue's first defeat yet before Ness's adventure. It tells a story of Giegue's descent into madness and the wandering band of aliens who once protected the Apple of Enlightenment, in a chapter-based format similar to Mother 3. This newly revised and rebuilt edition includes mountains of overhauled graphics, an original soundtrack, and many new and expanded areas to explore.
