It is endlessly hilarious to me that this game started off as an April Fool's joke that evolved into one of the best Yakuza games in my opinion. It still retains the excellent and engaging story from the other games, while keeping the perfect amount of room for the goofy side content that everyone's come to know and love. The new cast is excellent, and the main characters are even fully voiced in English! The English dub is fantastic with great performances from Kaiji Tang, Greg Chun, and everyone else. They even got George Takei as the main antagonist!
The only real criticism I have for this game is its gameplay, which has taken a bit too much inspiration from Dragon Quest. I believe that we, as a society, have moved past the need for an MP system dictating what we can and cannot do in battle. That being said, it's still definitely more fun than a lot of turn based JRPGs in my opinion. Even though it is turn based in name, it still has a bit of a real time element to it since people are constantly moving. It is kind of hard to explain all the moving parts, but just know that there is a ton of goofy shenanigans you can have in a turn based game with a physics engine.
If you're a fan of the series, then you should absolutely get this game. If you're not a fan of the series, then it's a great time to get into it.
