Its insane how detailed and involved this little side game is. It's like a game in and of itself. Part of me is happy to see such a cool side time sink to play around with, but part of me feels a little overwhelmed at how this game will potentially sink its teeth in and consume my time.
It can't really be surprising from the series that tends to go above and beyond in their diversions. I can't think of a Yakuza/Judgement that didn't have half a dozen other Sega games, shogi, mahjong, cho-han, blackjack, hanafuda, collectible card games, cabaret club management, and slot car racing, to name a few, each with their own powerups and rewards.
