Before you buy this one at at full price, know that the story campaign is half the length of the series standard, I completed ALL of it in 40 hours to give you the gist of it. For what it is outside of that you have the same yakuza formula, fun sub stories and most of its true and done minigames out there up for another revisit, nothing new that hasn't already been introduced, except for a new combat style which is honestly the thing I enjoyed the most. Tossing people around with spiderman wires plus ragdoll physics goes a long way!

As the title entails it is a supplemental sidestory explaining the events of Kiryu between Yakuza 6 and 7 while tacking in another obstacle and supportive characters to fill in the extra shoe in between to make the game its own little piece.
The story is effective, some better moments than others, but likely nothing you won't see coming if you've played the series long enough.

For Yakuza and Kiryu fans it is a decent trip back to series, given you have the right expectations for its shorter burst of content and identity as an interlude weaving towards something hopefully bigger and stronger.
