Starting the whole game over but keeping your overpowered character -- the victory lap of gaming.
New Game Plus (NG+) lets players restart the campaign while retaining some or all of their progress -- levels, equipment, abilities, or unlocked content. The implementation varies: some NG+ modes simply let you replay with your endgame build (power fantasy), others scale enemy difficulty to match (new challenge), and the best add entirely new content, story elements, or secret bosses exclusive to subsequent playthroughs. NG+ solves the problem of players wanting to experience the story again without losing their investment, and it gives endgame builds a purpose beyond the final boss.
Example
Dark Souls' NG+ ramps up enemy damage and health each cycle, up to NG+7, turning a victory lap into a genuine test of mastery. Chrono Trigger pioneered NG+ in RPGs and locked multiple endings behind it -- you could fight the final boss at different story points for different outcomes. Hades is essentially built around NG+ as a core mechanic, with the Heat system adding modular difficulty modifiers that keep each subsequent run fresh.
Why it matters
NG+ extends a game's lifespan at relatively low development cost and rewards your most invested players. It answers the question 'what do I do after beating the game?' with 'beat it again, but better.' For players, NG+ transforms a completed game from a trophy on the shelf into an ongoing relationship.
