The story explores a post-apocalyptic Gamindustri, with the Goddess Candidates banding together to restore order after Neptune's disappearance. The narrative has a more serious tone compared to previous entries, delving into the characters' struggles and the mysterious "Trendi Phenomenon" that threatens the world.

Character development is a highlight, with standout arcs for Nepgear as she grapples with the loss of her sister and the responsibility of leading the Candidates. The game also features two new playable characters created by renowned developers Ryukishi07 and ZUN, which add fresh perspectives.

The story features unexpected plot twists and references to past Neptunia titles, rewarding long-time fans while still being accessible to newcomers.

The real-time combat system challenges players to strategically manage their AP (Action Points) to chain together devastating combo attacks, rather than relying on button mashing. This added layer of tactical decision-making sets the gameplay apart from previous Neptunia titles.

The Lily System, which boosts character stats based on their relationships, encourages experimenting with different party compositions to maximize synergies. Optimizing these Lily Effects becomes a satisfying meta-game.

The disc development mechanic, where players create different game genres to unlock powerful abilities, ties directly into the narrative and provides an engaging progression system.

Multiple story endings, including a "true" conclusion, give players strong incentives to replay the game and make different choices to witness the full narrative arc.

A robust selection of side quests and achievements provides additional content to explore after the main story, further expanding the world of Gamindustri.
