Options are always nice.
Today's Xenoblade Chronicles 2 Direct revealed that a free launch day DLC pack will include the Japanese Voice track.
A new story trailer featured the Japanese cast with English subtitles.
Hurray! I have a microSD card ready to receive.
I was very confused by this news in the direct. I thought it meant that it would only have japanese voices. That would have been terrible. I want voices I can understand and I hate subtitles.
Outside of super Japan-oriented games such as Tokyo Mirage Sessions, I wouldn't ever worry about Nintendo games not having English voice overs.
