Disgaea is a video game series of tactical role-playing games created and developed by Nippon Ichi. The series debuted in Japan on January 30, 2003, with Disgaea: Hour of Darkness, later re-released as Disgaea: Afternoon of Darkness and Disgaea DS. One of Nippon Ichi's most popular franchises, it has branched off into both a manga and anime series. The Disgaea games take place in a fictional universe called the Netherworld and are known for their uncommon RPG elements, such as complex gameplay, extremely high maximum stats and humorous dialogue. Main characters in the series often include cynical, power-hungry antiheroes forced to fight alongside heroic foils, much to their disdain. The Disgaea series has sold 1.7 million games as of November 2011.
