How does a video game work

Well, a video game works very complexley. The data is all on the disk unless saved to the game console(this can only be done on a playstation 3). When you insert the video game disk into the game console, there is a laser light that reads the disk. The data on the disk is then ejected onto the screen and connected to the game controller ( so you can control your video game person). 3-D games are not really 3 demensional, they just look 3 demensional. they are data specs projected onto the screen and change color when activated by the game controller. And that is how a video game works.
