The Box Acronym is one of my oldest and most favorite Bungie Games of all time! I was still just a young'n when I first noticed one on the Marathon Infinity Box. No matter who has joined or left Bungie throughout the years, the acronym has been a constant, Rock of Gibralter-like, stalwart, Legacy.
In this increasingly digital-only world we are living in, it makes me sad to think that there soon may be a day without the Bungie Box Acronym (proper) :(

I was able to spy the acronym on product images of the Destiny Collection case and it is the same for PS4 and Xbox One

Any guesses out there?
