It improves on the gameplay of Yakuza 3 so much with some really fun combat and mini-games and the new main characters here are sick while having some great moments in the plot but oh my god does the storytelling quality take the ugliest nosedive I've seen in the series. The plot twists are comically excessive and almost predictable (with one twist in particular being really badly handled, you will know it when you see it), certain story aspects aren't as fleshed out as they should be or just had virtually NO build-up to them especially towards the end of the game, Kiryu's overall involvement in the plot, and the story becoming way too convoluted for its own good. The ending just ends up feeling unearned because of these elements so you just end up with an incoherent messy story shooting too high for the stars. It's my least favorite of all the Yakuza/Like A Dragon games by far but at least the soundtrack is baller though.

Also insane how 3/4 of the final bosses are pretty cool but then you end on the worst boss in the entire franchise by throwing an entire squad of enemies who collectively jump and stunlock your shit while the boss keeps shooting you to hell. Straight up stupid ass fight.
