Disgaea 3 is a sequel to Disgaea, a hardcore, turn-based, strategy RPG popular on the PlayStation2 and PlayStation Portable. In Disgaea, character units have a limit to their movement and attack ranges, based on level and weapons equipped. There are other special game factors that let you take advantage of the 3D battle map, many of which are unique to Disgaea.

One of the many new feature to Disgaea 3 is the addition of a Geo Block, which creates a 3 dimensional battle instead of the traditional 2D. Geo Block is a cube-shaped terrain-altering object. Players can use it to access and attack enemies where normally they cannot reach.

Geo Panel is a group of stat-altering elemental properties that are placed upon certain parts of the battlefield. When there are one or more colored panels on the battle grid, it means an element can affect that area. The effect can boost or reduce your unit’s stats. Item World is a special randomly-generated battle stage within each and every item you find. By defeating these special battle stages, you are able to strengthen your items.
