If you think about a great director - Spielberg, say - consider that he honed his craft on the back of almost a hundred years of technical, artistic and critical history. The first film camera was invented in the 1880s. By 1920 film was an art form on the rise, taking risks, learning its boundaries. By 1950 it had become the premier medium, with a voluminous body of criticism, different schools of theory and hundreds of thousands of examples from all over the world.
This means that videogames have 20-30 more years before a decent comparison can be made to films from the 1950s.
And Spielberg works in a sequential, non-interactive medium whose final output has to grab attention for, on average, 2-3 hours.
Let me be kind and assume that technology is progressing a little more rapidly each year and that our increased ability to communicate is driving innovation and criticism faster than in the early years of film. Even a conservative estimate would mean that in, oh, around 2060 games will be on par with the movies of today.
Unless you're like me and think it's all bunk and the comparison doesn't even make sense.
Which was better: X-Com or The Wild Bunch?
