One of my all time favourite PS2 games was a comedic RPG called Disgaea: Hour of Darkness. The basic plot was about the Prince of the Netherworld, Laharl, waking up from a very long (years) nap, to find his father dead, and seeks to claim his birthright. Now an anime has been made the trailer is here, in the March 2006 block
This could be good. The production company "Dark Assembley", is named after the demonic senate from the game.
