Which roles typically contribute to the final product of a video game?

The response highlighting designers, producers, and graphic artists as key roles in contributing to the final product of a video game is accurate. Each of these roles plays a crucial part in the game's development process.

Designers are responsible for the overall vision of the game, including gameplay mechanics, user experiences, and narrative elements. Their work shapes how players interact with the game and ensures that the gameplay is engaging and enjoyable. Producers manage the project, coordinating between different teams to ensure that the game is developed on time and within budget. Graphic artists create the visual elements of the game, including characters, environments, and user interfaces, which are vital for establishing the game's aesthetic and appeal.

Together, these roles directly affect the game's creation and quality, making them essential contributors to the final product, whereas the other roles listed, though valuable in their own right, do not directly engage in the creative process of developing the game itself.
