I was going to write a big article but I'm tired.
So I'm just going to say this...
The Film Industry is destined to meet a point where innovation will cease to exist. Despite smell-o-vision, taste-o-vision, feel-o-vision, the highest fidelity sound and video, CGI actors past the uncanny valley, there will be a point where we reach the limit of passive entertainment.
On the other hand, the Game Industry is destined to continually innovate. The way we interact with the world, with computers will always change and progress. There will never be a point where we stop at a level of interaction.
Though there are many other points, it is for those reasons alone that the Game Industry will topple the Film Industry and provide the more awe-inspiring moments we attribute to film today. There is no uncertainty about it.
People will forever love film. The passive nature of it will always fit a part of our lives. This is similar to how listening to music will never diminish because we play it.
Still, considering the difference in scales of innovation, games are going to provide the more visceral experiences. They may not account for the greatest stories ever told, but they will be more memorable, more tangible and simply put, more addicting than any other. There will be a point where games will feel like dreams or nightmares and nothing can beat that.
