In the run-up to the launch of GTAIV, there was an exclusive sneak peek that aired as a special on G4. I really don’t remember much other than (IIRC) Adam Sessler and Morgan Webb from “X-Play” watching a demo of the game and fawning over the fact that the player character’s feet had collision detection for curbs on the street. I cannot find any recordings of the special, but here is a link to a post-press release news story: www.vg247.com/g4-showing-first-gta-iv-gameplay-footage-this-sunday
