I started with 0, maybe got to chapter 5 or 6. I have Kiwami sitting on my shelf. Then 6 game out and sucked me in. Us I have Kiwami 2 on preorder. And finally, before even all of that, I have 4 and 5 on PS3 from when they were free at various times on PS Plus. Somehow I feel those ports of 3 - 5 come out outside of Japan, since they're just remasters and not remakes like the Kiwami games.
