How delusional do you have to be to think this isn't a great starting point in the Yakuza series
If you're not a complete faggot that's going to complain about how dated the previous games are when you go back and play them, sure, it's a great starting point.
I started at 3 and found it more enjoyable than 0. 0 has a lot of fluff in its content and I got far too invested in one storyline over the other. Still haven't finished it. It felt a bit like playing two games at one, but I couldn't play the one I greatly prefered.
