"So here I am, chasing some idiot through the streets of Versailles. He's a thick-witted, half-literate ruffian, quite unlike my sharp-eyed protagonist Arno Dorian, and yet somehow he seems a lot better than me at the simple act of running.
"Sure, Arno may be faster, but when he runs he has a maddening habit of suddenly leaping onto nearby scenery, often getting hung up on a bit of scaffolding or some kind of elaborate masonry. I just want him to catch the thug who stole his memento, to run along the same path as his quarry, but regardless of my intentions Arno takes the slightest deviation from the target's route as a prompt to make a flying leap for the nearest ledge, or cart, or building, or whatever." -USG
