Disgaea 3

Re-released for the PlayStation Vita in December 2011 in Japan and 2012 in other regions with all downloadable content from the PS3 version available at launch.

Disgaea 3 is a tactical RPG; most of the game involves battles on isometric maps upon which the player controls a group of characters. Maps often feature "geo blocks" with statistical effects on the battlefield, that, unlike in previous games, can be stacked or stood upon. Many objects in the environment, including these blocks, and characters themselves, can be lifted, thrown, or destroyed. Certain classes can create boxes or barrels to create stepping stones. Characters can form stacks, allowing them to reach higher areas or perform "tower attacks". When throwing a character to a monster-type ally, they will bounce an extra distance based on the monster's direction and throwing stat. With the newly introduced "magichange" feature, monsters are able to transform into specific weapons in which a partner can use to execute a strong technical attack. To do this they must be assigned to the same club as the ally, and the change is temporary. After two turns the monster disappears from battle, unless in the magintology club which increases it to 3 turns. Characters now have certain weapons that they are proficient with, much like Makai Kingdom's battle system. While characters can use other weapons, they won't be able to use the weapon's skills. Weapon skills are now unlocked by purchasing them with mana collected from defeating enemies. Many of the skills' effective areas have been rearranged, and each weapon now has two hidden skills. One can incorporate a maximum of two special augmentation abilities, known as "evilities", to improve a character's performance in battle. One skill is standard for each class, the second skill can be customized. When a monster executes the Magic Change skill, their main evility is also transferred to their partner. Bonus maps and characters can be accessed after the final boss is defeated, at which point an epilogue chapter opens. The player may choose to continue to the extra maps, or to replay the entire game with stronger characters as in previous titles. From within the epilogue, many extreme challenges await hardcore players under various circumstances, from maxing out characters to the millions, to defeating the final secret boss and then the land of carnage.

The game takes place in a Netherworld school called the Evil Academy. In this demon school, a good student is one who engages in evil activities such as truancy, never showing up to class, and getting in fights with others. The student who participates the most in these kind of activities is known as the Honor Student, while demons who are admirable by human standards are known as delinquents.

Mao, son of the netherworld's Overlord, has not once attended class since the beginning of school. His ambition is to overthrow his father and claim his title (along with claiming revenge for having his gaming systems destroyed). After reading a few volumes in his manga about the Super Hero, Mao resolves to become a hero, convinced that it is the quickest way to gain enough power. Eventually, Raspberyl, Mao's childhood rival, learns about his goal, and realizes that if Mao became a Hero, it would endanger her position as the academy's top delinquent. She makes up her mind to stop Mao's plan to sustain her title. However, since Raspberyl is a demon delinquent, she tries to solve the problem without violence and talk him out of it instead. Almaz, a meek hero fanboy from Earth on a mission to protect princess Sapphire by defeating the overlord who he believes is targeting her, misunderstands the situation and tries to save the day. Mao accepts the challenge and defeats him, stealing Almaz's title and giving him the title of "Demon". Almaz slowly starts becoming a demon, but he sticks with Mao, who claims he is his slave now, to defeat the overlord. Visiting the "Heart Bank", in which demons store parts of their heart and memories to be less feeling, they make several attempts to open up Mao's heart, where the hero title is stored, but are unsuccessful. Geoffrey, Mao's butler, is unhappy with Almaz's meddling. At one point, Mao comes across his sealed memory of him contributing to his father's demise by telling the Super Hero Aurum his weak spot. Aurum later clarifies this by revealing that the Overlord intentionally lost in order to protect Mao from his ultimate attack. Eventually, all the freshmen become delinquents, being brainwashed by the Senior class. After fighting them, Mao learns that Geoffrey orchestrated the plan. Actually the Super Hero Aurum in disguise, Geoffrey attempted to raise Mao to be the ultimate overlord so he could eventually destroy him. Mao tries to get revenge by destroying the human world, but the words of his friends convince him not to release the evil in his heart, and he instead goes after Aurum, who is disappointed to see Mao has not succumbed to evil. Aurum initially dismisses Mao as weak, but Mao uses the power of a hero to defeat Aurum. The ghost of his father gives Mao the Overlord title and he runs the Evil Academy henceforth.
