Concept video leaked. Pretty cool parkour. Concept videos are interesting, I think as the engines get stronger and stronger it's coming more and more to the artists saying: "what would be the coolest game to play" and making a little video of it, and then the programmers figuring out how to do it from there. Star Wars and Assassin's Creed same thing. Video Games are always growing so fast it's fun to see the new possibilities coming, wonder how much longer until games are bigger then movies.
