"Yakuza 5 is that includes all the Japanese DLC, including “Another Drama” which is a series of extensive sub-plots that focus on each protagonist. Whether you are training for dance battles, ferrying people around as a taxi driver, or even helping out as a temporary ramen cook, there’s a whole world to explore! Head into CLUB SEGA and play some Virtua Fighter 2 with your friends over PSN. If you prefer to play something more rhythmic, you can check out Taiko no Tatsujin and drum to the beat of some music."
