Akudaikan (roughly 'The Great Villain') puts the player in the shoes of a corrupt businessman who must expand his commercial empire by resorting to morally questionable methods, in a dark-comedy key about Japanese corporate life. It's a management simulator with acid humor, Japan-exclusive, far removed from the genre's usual friendly tones.
Today it's a niche curiosity, valued by those looking within PS2's Japanese catalog for titles that break away from the usual sports or RPG mold of business simulators.
