Which ones have you played? For me it has been 1 & 2 on PS2 and 3 and 4 (which I am playing as we speak) on PS3. Really love Kazuma's story line, so many ups and downs. The series really helped me cope with the lack of a Shemue 3. I heard that Yakuza 5 will be showing it's head stateside soon. Have you played Ryū ga Gotoku Kenzan! or Dead Suols and are they worth getting? Thanks for your input.
