Well its certainly a more chill experience for the first few chapters. Where as TLOU2 went one way, Yakuza is very much more about the opposite in the orphan sections, its slow, but a really nice experience.
The one thing too many people overlook about the combat (and then complain about... lol) is that in this game you can get major powerful upgrades really early in the game (around chapter 4-5) - so basically look up the details to all of Komaki's training - as it lets you get all the best counter moves really early in the game - that includes the legendary Tiger Drop which is amazingly strong in this game AND can bounce people off of walls for follow up combos. So get it early and learn its timing to mess people up.
Other than that, just dodge behind people and attack them from behind (like, every Yakuza game) as this solves the more block happy enemies. Its really not hard or all that frustrating, I'd say its more a mix of people button bashing mindlessly and just not upgrading Kiryu. You get more than enough XP early on to unlock tons of moves, though it is worth leveling up in the first Kamurocho area before heading for the boss, because like many Yakuza games it forces you to unlock the stomp heat move (triangle when enemy is on the ground) which you'll use in the first couple of chapters before you get good moves.
3's got excellent combat if your willing to learn how it all works... Or just play it on easier difficulties, because hard mode actually isn't easy mode no.3 in this game!
Playing 3 on hard and getting the upgrades early results in the most perfect difficulty level of any Yakuza game. Fights are challenging but not unfair. People are missing a lot by breezing through on easy and writing the game off.
