The Infinite part of the name did seem to hint at it being a pretty long game.
When the developers describe the game’s length as « monster class », you know it’s going to take a lot of hours. That’s exactly what Like a Dragon: Infinite Wealth needs, according to Ryu Ga Gotoku Studio boss Masayoshi Yokoyama. He describes it as a « monster-class game longer than anything we’ve made so far » and that it’s not something that can be played through in one or two all-nighters.
