Yes. That’s the order they were written and released in, so the story elements will fall into place correctly if you play in that order.I got all from 0 through 6 on PSN. So, I should play 1 to 5, then 0, then 6 for the best experience?
To really make things have the right impact, I’d even suggest leaving the Majima Chrincles chapters of Kiwami 2 unplayed until after you play 0, as that plot line pays off some things from 0 due to K2 being made after 6.
