... I have every game except Yakuza 3 to play. I HAVE played like, halfway through Yakuza 4 many years ago but stopped for whatever reason, so I'm gonna' have to revisit that before I can move onto the other games. I'm still torn on which order I want to play them, release order means the gameplay will get progressively better, but chronologically means I won't be jumping all over the story. Although I guess it worked for Star Wars, so I think it's safe for me to play them as 4, 5, 0, 1, 2, 6... that way the games will get prettier and the gameplay will improve everytime I start a new one, lol.
I REALLY need more time to play games though lol, just the stories of Yakuza games alone clock in at 40-50 hours according to HowLongToBeat, if I'm super lucky I could make it a game a month, but I'd be burned out and end up slowing down later on lol.
That's exactly how I've been planning on tackling them, having finished 3, 4 and 5 already. It looks like we both started with part 3. Although I may move Yakuza 6 to the head of the line, just to wrap up the main story. Not sure if i want the ending for Yakuza 5 to be left dangling for such a long time. I finished it in April 2017. So yeah, maybe 6 next.
