Yakuza 0 is "comfortably the best, funniest and most heartwarming game about a desperate battle over real estate", so says Phil in his 90-scored review. That sentence alone offers insight into the action adventure's quirkiness—which is what Sega Europe's John Clark suggests makes it work in the west. 

Chatting to gamesindustry.biz, Sega Europe's executive vice president of publishing reckons Yakuza 0's commitment to its original vision is responsible for its success. Languid conversations, weird minigames, and a "world where the sublime meets the ridiculous and the ridiculous is sublime", and all.
