Where is the Shakespeare of cinema you mean?
Or the Homer of script writing. Or the Bernini of film editing. There are none. And it is even questionable whether "Citizen Kane" is the "Citizen Kane of Cinema". These parallels, as amusing as they may be to some, simply do not exist in a degree of accuracy that makes them worthy of being pursued. Each author's contribution is unique and derives from very specific circumstances which can never be repeated.
In addition, Cinema accomplished more as an artistic medium in the first few years of its history than games have in four decades as an entertainment business. As we know, "Citizen Kane" represented a sizable advancement in film, in story-telling, photography, and so many other aspects of art and human creation in a far broader sense. No single video game has ever - or, the way I see it, could ever - have a comparable cultural impact.
