@[email protected] I've also started with 0. There's a bit of a learning curve over the first hour or two, but the characters are great, and I'm really enjoying it. I'd say you get used to the limited save facility, but be warned that it's a big game - I'm only maybe a quarter of the way through so far.
@[email protected] I was in the same boat until last year. I started with 0, despite not being made first, it felt like the natural place to jump in. Alternatively, maybe Yakuza: Like a Dragon since the fighting changed to turn based in that one, which is more my style.
