Like a Dragon: Infinite Wealth has a New Game Plus mode, but not all progress is transferred into it. New Game Plus is a common feature in RPGs with level-based progression. It allows players who have beaten the game to restart it, maintaining some of their progress. NG+ can include extra content, new difficulty levels, or, at the very least, an opportunity to make different story and character choices. In short, it's a way to keep repeat playthroughs fresh, and has been a staple in the Yakuza series for quite some time.
