The Yakuza 20th Anniversary Edition bundles three foundational entries in SEGA's crime drama series: Yakuza 0, a prequel set in 1980s Japan following the origin stories of Kiryu Kazuma and Majima Goro; Yakuza Kiwami, a modern remake of the original game where Kiryu investigates the theft of 10 billion yen in Tokyo's Kamurocho district; and Yakuza Kiwami 2, which continues Kiryu's saga as he mediates a brewing war between Tokyo and Osaka's criminal organizations. All three games feature beat-em-up combat, detailed city exploration, and various side activities within a narrative focused on honor, loyalty, and power in Japan's criminal underworld.
