>>29106I agree with the other anon, Yakuza 0 is a great starting point. Yakuza 0-6 are also altogether $35 on Steam and GOG right now so it's the perfect time to jump in.
The thing about the Yakuza series though is that you jump from a modern game to an outdated one if you play chronologically a few times. 0 sets the bar really high but the series doesn't really hit peaks like that for a while. 1 was a hasty remake, 2 uses the latest engine but has iffy combat, 3 is the oldest title and has poor combat, 4 is where the series starts to pick up again, 5 (for me personally) was amazing and up there with 0 and I'm currently on 6.
In terms of story, I feel all of the games are 8/10 or higher, cheesy plot twists be damned. They all made me feel emotional more than once per game.
