Because I do. They are quite possibly some of the best games that Sega has put out in recent years. It's basically something like Shenmue but with more emphasis on fighting. And some of the side-missions are either fun or insane (especially one of the side-missions on Yakuza 2). Also, Kazuma kicks ass! And the YF6 mini-game on Yakuza 2 is awesome. So, post your opinions on the series here!
