Playing through 3 now on my Xbox, so far so good. I've found after playing 0, kiwami 1 & 2, and 7 that the story in a Yakuza game is always worth playing through. There are rough parts of 1 even in Kiwami but that didn't take away from the story. I'm playing 3 on easy and plan on doing that for 4 and 5 too, though 6 I'm planning on playing normally.
