I am making my way through Yakuza series right now and while playing 5 I realized that I am not that invested into the game’s combat, so I turned it to easy and that just streamlined the combat so much for me. I would recommend to maybe try Yakuza 0 on normal at first and then just switch it to easy if you feel like the gameplay might be dragging on.
I think that’s my main complaint with the game. Once you find a way to beat the boss, you just go for that build every time. It’s so punishing and the path to get there is so long, that it’s a massive disincentive to try new things.
