Something that stood out to me is how the development of game graphics roughly parallels the development of animation earlier in the 20th century, from black-and-white to color, and then rotoscoping, multiplane (in games, it’s called a parallax effect), and then, increasing complexity of characters and realistic effects.
Games, however, also boast their own unique graphic language that extends beyond traditional cinema. Whereas in its early development, gaming borrowed a lot from cinema, the roles have reversed now.
