The following is a promotional video for the upcoming game Deus Ex that gives a (very) brief look behind the scenes. It contains a lot of pretty pictures and sheds some light on their approach to storyworld creation.
It’s pretty light on the content but I found the fact that they created 100 fictional brands for their world a nice detail. I do hope they provide more behind the scenes videos or maybe some interesting material bundled with the game/collector’s edition.
