All things considered, though, Yakuza 4 is an excellent title that proves why this series, underappreciated as it is, is one of the crown jewels in Sega's current game lineup. It's not quite as big an upgrade as some series fans would have liked, and that might be a bit disappointing. But look at it this way: sometimes with a sequel, you don't really need or want a lot of major changes or upgrades. What you want is simply more of what made you love the series in the first place. And in that regard, Yakuza 4 delivers a knockout blow.
