Yeah, I heard about this rating not too long ago and posted on it here:
batman-arkham-knight-vt9681.htmlAccording to one of the story links posted in the above topic thread:
https://games.yahoo.com/news/batman-ark ... 00573.htmlit seems they may be taking Batman to some "dark" places in the game that some people may have problems with, thus the M rating, sort of. I haven't played the game either so not sure exactly what features makes it have this rating. Seems out of character for something labeled "Batman", but you never know. And, it's sad that some younger players may not be able to play the game due to the new rating.
Interesting about the musical director.
