What is the least replayable game in the series for you?

I've played 90% of the series as of now. The only games that I've never played are Infinite Wealth, Ishin Remake(altho I've beaten the OG version) and Fist Of the North Star Lost Paradise, and yes, it counts.

I am a huge fan of Yakuza games, been one for probably more than three years, and to be completely honest, I really don't like revisiting one of the games.

I am a fan of OG games that were released on PS2, more than the Kiwami versions, especially 2, I loved 3 on my PS3 to the point of replaying the game several times(and also it was the first game in the series for me lol), and I pretty much love every other game after it, minus 6 that I don't really like, yet still kinda do. It's complicated.

But there is an exception. Yakuza 4.

I don't know what is the deal, but this game is just... Kinda nothing to me. I loved the Akiyama part, and the Final boss on Kiryu's side, but everything else is just kinda bland for me. This is the game for me that has almost little to no memorable moments, unlike every other game before and after it. The only things that I can say were memorable to me were some of the boss fights, the coliseum cutscene in Saejima's story and probably Kamuro Hills battle, but I'm really not sure.

So yeah, this is really weird to me, I can find reasons to replay even 5, and I'm talking about the sheer massiveness of the game, I replayed it more times than Yakuza 4, as in 3 times on Y5, and 1 on Y4. Yeah.

And it makes me wonder, do any of you guys have a case like this for one of the games, or several of them? I'm kinda interested in this.

(Altho many of you would probably say 3 or 5 is this game for you, I just feel it.)
