Most of what comeson a game disc is merely code that renders polygons, ai, etc. in the game. The only thing that takes up a lot of space is the textures that go on polygonal models, and the audio. However, games often use repeat textures and sound bytes, stuff like that, so they don't need that much on a disc.
Moves, however, are essentially thousands of 1080p images (and the sound that accompanies these images), each of which are unique. Games wouldn't need near that number of images (or textures, in a game's case), and they'd rarely be that large.
Imagine a ~2:00 hour movie, showing 24 1080p images a second. You'd need to save 172,800 1080x1920 on a single disc. That's a hell of a lot of space. Just look at the size of any of the pictures on your desktop for comparison.
Basically, a movie contains pre-set images. A game contains the code to render such images, which takes up far less space. |
It´s not that easy. If your example is right, a movie would be about 350 GB big. Even Blu-Ray aren´t THAT big. Truth is, even movies on Blu-Ray aren´t raw data, but are compressed.

Actually the data that is shown is still those images even if they are compressed. Whats different is that you can compress also in third dimesion when compressing movies.
And games can be rendered in any dimension, because those 'pictures' they make on screen are actually made real time by using some objects & other stuff. Games aren't even near 1080p resolution because it would require too much from GPU:s. Of course one could make game that works in 1080p resolution, but the tradeoff would be simpler graphics.
