Atlus USA is generally thought of as a niche publisher - after all, with the release of games like Shin Megami Tensei: Persona 3, which features Japanese high school students shooting themselves to summon demons, and Operation Darkness, where lycanthropes fight Vampire Hitler, Atlus publishes titles that could be considered off-beat - at best. However, two of their titles for the PlayStation 2, Disgaea: Hour of Darkness and Odin Sphere, have achieved mainstream success and will be receiving the Greatest Hits treatment.

According to retailer Amazon.com, both titles' Greatest Hits iterations will be available on September 2 for $19.99 USD.
