Just browsing reddit and discovered Kiryu keeps a blog in Yakuza 3??? I's part of the system for learning fight moves or something
Yakuza 3 leans further into absurd jokes as well via the Revelation system, which might be the first blogging-based progression mechanic in games. Basically, Kiryu sees something amazing happening, like a woman miraculously surviving a motorcycle accident while daydreaming about a man on a billboard, then realizes how to translate what he saw into a fighting move while typing out a blog post on his flip phone.
