Great Changes in Yakuza Games (That No One Ever Talks About)

People normally talk about stuff like better graphics, new mechanics and other more apparent features. Me? I drool over little things like a staircase in a Korean BBQ place.
Can you think of something similar? I could think of things like toggle sprint in Judgment (which I've discussed before) and UI adjusting for the PC versions of the games that makes recording on Ultrawide better lol.
