Graphics evolution Before, in 1942, video games used to be in 2D and pixelated (left image), created using a cathode ray tube.
Now they are in 3D with a more realistic image (right image): 3D is created using LISP machines, Paintbox computers and work stations like Silicon Graphics.
Before, the music in video games used to be monophonic, looped and completely digitalized (using a specific microprocessor to create sound waves and sound effects) due to how expensive were cassettes and gramophone records at that time.

Video game control Before, the video game control used to be with a simple controller with some buttons.
Now there are controllers with movement sensors or optical sensors.

An example is Batman: Arkham Asylum. Also, next year, the Nintendo 3DS will be released, it's games will be in 3D, with no need of special glasses. What will happen next? Who knows...
