How are video games were created

They are normally created by computer animation, also known as "CGI", which is created by artists, all pieced together by the supervisors, to create a video, to then be developed on a program, which is then interactable, with a sprite, who you the game player are, which you can interact with, fight with, or talk to. This is then put on shelves all over the world and sold to you, the consumer.
