Story and voice acting.

I'm enjoying the plot so far; I'm playing with pleasure. I also have no complaints about the voice acting – I'm not too picky. I started the fifth game a couple of times, but I just haven't found the time – and then, suddenly, I did.
Although I agree that sometimes the actors have to rush to fit within the time frame of the English version. Because, as I understand it, the point of localization is that the audio files are the same size and duration so that it's easier to replace them.
