I just finished Yakuza 3. I have loved 0, 1, and 2. 3 was tough simply due to the lack of music cues. There is so much time spent listening to "ambient_beach.mp3" or "bustling_small_city.ogg" that it was getting tedious.
The story is great and it shows off a side of Kiryu that hadn't been developed and was great fun to see. The gameplay was so-so. Stiff and of the era. I'm currently taking a short break before I dig into Y4. I'm really excited to get up to LaD and that game style, but I am enjoying the story to get there.
