Artists make the characters and scenery. They may draw, mold from clay or photograph. Animators make the characters move. Computer programmers put art, animation, and the story together to make the game. Composers write the music for the game.
Sound programmers make game sounds using a keyboard.
They connect the sounds and music to actions in the game. Testers play games for weeks to find problems in the games so that nothing goes wrong. I asked the 100 second graders at my school, Hilltop Primary School, about their video game playing, using a paper and pencil survey I made.
