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 spend the entire game prepping for the boss. Just because I can ohko every other ship the moment I land doesn’t mean I can touch the beast. I’ve done the last sector without taking a hit just to never even get past the shields in phase 1
