As always, Like a Dragon conjures up memorable tunes, although a lot of them have been carried over from previous games. Voice performances (especially the native Japanese language version) are excellent, too.
The series has never been a slouch when it comes to visual loveliness, but Infinite Wealth kicks things up a notch, with rich, detailed character models and environments. Considering the sheer amount of content here, it's remarkable that the level of fidelity is consistent throughout.
If you enjoyed the turn-based RPG action of Yakuza: Like a Dragon, then the evolution of those systems in Infinite Wealth are sure to delight. That's when you're not wrapped up in the myriad diversions peppered across Honolulu and Ijincho, of course.
You can't have too much of a good thing, and that rings true of Infinite Wealth. The issue is that it's all thrown at you during the game's opening chapters. Miss Match dating, dungeons in the Labyrinth, Dondoko Island, Sujimon... It's a lot.
Not a particularly imaginative list – you'll have done much of this before. That said, it's good that you're pushed into trying out everything that Infinite Wealth has to offer, and there's no need to achieve 100% on the completion list. Phew.
