What I spoke about is the importance of active story-telling - by which I mean the various methods game developers use to give a game narrative without allowing that narrative to interrupt play. Another way to do that is to have far less narrative, and that works for some games - both western and eastern.
What did you mean when you said?
Nier's story telling is unique along with MGS 4th wall breakers(the best kind of story-telling and both the west and east should learn from it IMO).
What do you feel is unique about Nier's story-telling exactly?
Also, I am weirdly not a fan of the MGS series. I was a fan as a little kid back when I played my Dad's copy of Metal Gear: Solid, but I was bored by MGS 3 and haven't played them since (this may be a generational thing as my Dad still loves them). How does MGS 4 break the fourth wall and how does it relate to your point about Nier?
