Hurrah for Nippon Ichi. Not only do they tirelessly serve the needs of niche enthusiasts with games like Disgaea, but they understand the cathartic value of letting you play the bad guys once in a while. Much like the Disgaea series, in fact, both "What Did I Do To Deserve This, My Lord!? 2" and its Batman-rankling predecessor put you in the shoes of a divine evil - sallying forth against the sickeningly puritanical forces of goodness and light, turning the traditional RPG hit-tables with a healthy splash of comedy villainy.
We'll be calling them the "Lord" games, by the way, for obvious reasons.
In both Lord games, players take the role of the God of Destruction, via the medium of a disembodied pickaxe. Summoned by the camply comedic dungeon master Badman, it's your job to mine an evil lair from the magical loam and bedrock below a typical fantasy JRPG kingdom, constructing a labyrinth of sufficient terror and complexity to confound the aims of the occasional visiting hero.
