Disgaea 6

The game involves turn based combat on grid-based battlefields. There's a lot of focus placed on effective management of the in-depth systems that surround that combat, and individual characters can reach high levels, up to 99999999, and be able to perform 10000000000000000 (10 quadrillion) damage in a single attack, which are much higher values compared to previous entries in the series. Some of the new features of the game include auto-battles and the “Demonic Intelligence” system: each character starts with a set of pre-programmed AI routines that the player can choose between, but they can also build additional routines for them from scratch or by copying an existing routine. There are several classes the player can build characters around. There are a number of management aspects in the game, including a senate chamber in the main hub where monsters and demons from various fictional political parties vote on the underlying rules of the gameplay.

For the first time in the series' history, the game uses 3D graphics for both battlefields and characters.

The game follows the story of Zed, a zombie who is on a quest to defeat the God of Destruction terrorizing the Netherworld, a parallel universe inhabited by demons. There are multiple Netherworlds, each ruled by a different overlord. Zed has lost to the God many times already, but every time he dies he is reborn thanks to a power called "Super Reincarnation". Every time he gets reincarnated, he gets slightly stronger than he was before. After each death he is taken to a new world, where he meets a new companion, and attempts to defeat the God of Destruction once more.

Disgaea 6: Defiance of Destiny and Complete received "mixed or average" reviews according to review aggregator Metacritic. Nintendo Life gave a positive review, arguing that the game is "easily the most streamlined and enjoyable entry in the series yet," giving the game a score of 8/10. However several reviews noted serious performance issues of the Nintendo Switch version. CGMagazine described it as the "weakest entry in the series", in part due to this.

The game sold 23,551 physical retail copies on Switch and 15,761 physical retail copies on PlayStation 4 for a total of 39,312 copies sold within its first week of release in Japan.
