Yakuza 6 has yet to be beaten as my best Yakuza of all time.
I've been a fan of the series since 2006 and I've never thought we could reach these heights, the story is amazing just like the cast which is one of the best, if not the best in the series.
My only nitpick is that we didn't get to have the soundtrack of the JP version with Yamashita-san songs, the emotionnal impact of the ending is just not the same without Soubou so I recommend to at least check that cinematic in japanese after seeing it in english.
Started as a honeymoon, it was my GOTY at the time. Then they dropped the ball pretty quickly with the content and lackluster seasons, right before/after the Hot Wheels stuff released. Which was fun but again the same thing we've already seen.
Instead focusing on making sure getting money stays a grind fest as much as possible.
What you get is still undeniably great, just don't expect to stay too long.
