Based on classics like Mega Man and Super Ghouls 'n Ghosts, Prinny is an old school game with a new coat of paint.
Fans of Disgaea are already quite familiar with the Penguin-like creatures known as prinnies. Dood is their signature word and they have a tendency to explode, due to the highly unstable nature of the souls which have created them. Prinny is an upbeat character that most players can't avoid falling in love with, and as such, it makes sense that NIS decided to take the character and spin-off an original title based solely around them.
