Segagaga

Segagaga (stylized SGGG) is a role-playing video game. Its storyline makes tongue-in-cheek references to the commercially unsuccessful Dreamcast console - the player is recruited by Sega in a last-ditch effort to stop a rival company from taking over the console market. The game, interspersed with animated cut scenes, features numerous cameos by Sega characters and games, as well as a variety of gameplay styles. (wikipedia.org)
