I highly recommend giving the games a try, they really are gems that used to be hidden until like 2015 when Yakuza 0 dropped (an amazing place to start the franchise), I really recommend messing around with Yakuza Kiwami 2's mods too, as Yakuza Kiwami 2, and Yakuza 6 have sorta dumb fighting engines compared to the combat games like 5, 0 (And kiwami, since K1 runs off the same engine and the same 4 fighting style combat), or 4.
Yakuza 3 has pretty good combat too, but the game is super slow starting off, and in the remastered version (The only version on steam) Enemies like to block a lot and you won't be able to break blocks easily until you get your hands on some of the early game upgrades.
