Ryu ga Gotoku 2
PS2 only — no modern port or Steam achievements. The Dragon Engine remake Yakuza Kiwami 2 covers the same story.
Widely cited as a fan-favorite peak. It moves between Kamurocho and Sotenbori (Osaka) for an all-out Tojo–Omi war and the 'Dragon vs. Dragon' clash between Kiryu and Ryuji Goda.
Detective Kaoru Sayama joins as a rare, substantial companion-heroine, and Ryuji Goda became popular enough to return in later titles like Dead Souls.
It established formulas the series reuses for years: the Osaka setting, a rival 'Dragon,' and sprawling clan-war storytelling.
This title isn't tracked for Steam achievements. It lives in the archive to help you understand the wider series and its world.
