Yeah, I agree, the voice acting is really good. In the past, I have had a hard time understanding why some people would prefer to play with the original Japanese voices, when they could have English-speaking voice actors and do without subtitles. I get it now. The emotional tone gets carried much better by the Japanese voice actors.
Have you seen the footage of Yakuza 6? After seeing the trailers/gameplay I'm really excited for it, yeah the framerate has been cut in half and the resolution is down to 900p on standard PS4 but they made a pretty big improvement in the visuals.
Just got done playing Kiwami for a few hours tonight, time really goes by fast when playing these games
