In an interview, the legendary film director John Ford made this remark:
It is wrong to liken a director to an author. He is more like an architect, if he is creative. An architect conceives his plans from given premises - the purpose of the building, its size, the terrain. If he is clever, he can do something creative within these limitations.
Even though it is a dangerous mistake to think of games designers as architects given the necessarily iterative aspects to software development, this idea applies equally well to commercial videogames. What we still seem to lack, alas, are visionaries like Ford or Kurasawa who can marry the challenges of the technologically-yoked commercial games industry with Ford's creativity-within-limitations.
