What's truly bizarre and off-putting though is how this game switches between several different types of cutscenes, ranging from completely fleshed out and animated (those look great) over less well-animated (but serviceable), to nearly completely static (but still voiced)= cutscenes with barely any movement.
If I remember correctly, 0 might be the only game to do this. 0 was my first game too and I remember being taken back by this (the static scene talking to some guy in a car smoking a cigarette or something is what sticks out in my memory). It's possible other games did this too and I just forgot, but I'm not sure.
As for 0 being a good starting point, I do disagree. Having played all of them, I think 0 would land better if it was played after 1, 2, and 3. Kiryu's and especially Majima's stories in 0 heavily reference things that occur or are at least revealed in 1 and 3.
I think the remake addresses these issues as well.
