I had to check that video out, since I hadn't caught that Mega64 vid (I've always loved the Tetris one) but after seeing that I must confess I'm going to go for something more sinister. I'm going to walk around, with my hands in my pockets, or the hoodie sleeve depending on my Templar Status, and have my head bent down. It's genius.
If it's like the "awareness" in Revelations I wouldn't doubt that for a second. Although it is making me want to continue playing the first.
