Video game documentary filmmakers Noclip have somehow acquired themselves a lot of boxes of tapes (remember those?) that they're now digitising—a decade's worth of video game history, mostly feature and BTS material, that was apparently headed for a landfill from the GameSpot vault. Among the initial batch of unearthed videos is this behind-closed doors demo of Knights of the Old Republic, from E3 2001 (remember E3?).
