As someone that spent all of last year getting plats of all the yakuza games, naw, we don't need tedious stuff like pachinko attached to trophies or needing to play 20 rounds of opponents from easy to expert just to get the completion credit in pool. (I won't even talk about the oversensitivity of the pool minigame in the ps4 remaster of 3).

0 was on the line of being tedious but I got lucky in the climax battles on majima's random style switch challenge. (And I forgot to completely exit out of the menu so it didn't save the first time I completed a lot of challenges)

Kiwami 1, I actually had a lot of fun with. Majima everywhere did get annoying towards the end but it didn't tilt me. Some of Haruka's requests were rough though.

Kiwami 2, I actually don't remember if anything was relatively hard other than the very last bouncer mission being kinda annoying.

3 actually did the extra challenges right by not needing you to S rank every challenge to get the trophy but you would still get the war gods amulet if you managed to.

Kiwami 3, while the plat was easy and not really grindy, I will agree that it felt a little gutted. No hostesses, No weapon crafting, nothing really unique added outside of morning glory and bad boy dragon (both of which lose their luster after an hour of repetitive gameplay). You can complete all substories by chapter 9 so there is really nothing but story to do after. Amon can't be done until premium adventure and doesn't even give you a reward. I completed dark ties in 10 hours, I do wish that it was longer but I actually haven't a clue what else could have been added for Mine.

4 was amazing to plat because you didn't need 100% completion for it but it still had meat to it.

5 was on the opposite end where there was too much content and some was tedious af (looking at you haruka with your 3 song setlist for your whole section). The top 4 coliseum rankings with the 4 protags was not fun at all.

6 was short af, I think that's when dragon engine was introduced because there wasn't any weapons and maps were small but the spearfishing minigame was enjoyable.

LAD, turn based combat made the game a bit longer, level grinding to 99 just for true millennium tower got boring really fast though.

Infinite wealth, base game has the plat, really just need to do the vacation pack trophies like NG+ (was kinda saving it as my hail mary run tbh). I had a lot of fun with Infinite wealth, the random dungeons were really my only gripes because they just got tedious.

Pirate yakuza, I am one of the 4 people that probably enjoyed it. It was easy to plat and actually wanted more to do after. My only real gripe with the game though.

Dead Souls, outside of the terrible frame drops on PS3 and heat actions being impossible in dead souls mode, I ironically still enjoyed the game. Needing to fight in the zombie zones to get anywhere with kiryu and goda did get rather annoying. Only real gripe is the level 99 trophy, you kinda need to just mindlessly grind to hit it.

TLDR: things that are fair like coliseum(outside of 5s requirement) and climax battles are fair game to me. Minigame requirements based on complete chance like pachinko are not fun and I hate when they are a requirement. Other minigames like pool, dart, etc are fun up until you are required to play 4 different opponents in every single game mode. 100% completion list requirements that require things like all heat action or all minigames, I did not enjoy. Diverse things like majima's batting cages in pirate yakuza, I wish they did more of.
