Set in a beautifully-realised game world, New Little King's Story follows the player as they assume the role of a King tasked with reclaiming his kingdom from an invader known only as 'The Nightmare.' King Corobo, a plucky 14-year-old royal, presides over a stricken land. The evil Nightmare is running havoc and the populace lives in fear as it preys on them. Thus, as Corobo, the user must unite their subjects in order to fight back and reclaim the kingdom.

New Little King's Story takes the form of a roaming role-playing title, with the player recruiting the isolated pockets of subjects into a unified army. The game allows the user to move freely around the scrolling player in the search for recruits and for items that will aid the quest. The touch-screen of the PlayStation Vita handheld entertainment system allows the player to control and arrange recruits and send them into battle or to search areas with simple finger movements, with groups of subjects easily marshaled and moved.

The world of New Little King's Story is packed with rounded characters, all of whom will play a vital part in overthrowing the Nightmare. Advisors and warriors will offer specific skills and attributes, adding skills to the growing army and enhancing their abilities. Similarly, the game map enjoys an incredible level of detail.Similarly, the passing of time is shown as day turns to night - with the subjects needing rest after their exertions, and the game world changing as Corobo's army grows, confidence returns to the land, and the subjects return to their normal routines as the tide turns against the Nightmare.
