Game Graphics Beyond Realism: Then, Now and Tomorrow
What makes a game interesting and fun to play? This is probably one of the most difficult questions to answer in the field of game development. From the gamers' point of view great graphics does not necessarily comes along with a great gaming experience. The time when astonishing graphics alone could sell a game is probably over. Due to constantly evolving graphics hardware, new visual effects are possible which more and more increase visual realism and immersion. Most games try to simulate the visual impression of reality as closely as possible. But this realism stretches only to a certain degree. In games we want to see heroes with superior abilities and hence, we are able to bend the laws of physics to fit the needs of the story. Why not also break the laws of graphical realism in order to enhance the visual experience? This paper encourages the use of alternative, more artistic rendering styles, such as non-photorealistic rendering. Some games already make use of a cartoon style rendering, but so far no other non-photorealistic rendering techniques have been adopted. These methods can be used for artistic purposes to capture the style of other media (e.g. comics), and to assist in storytelling by changing the style used throughout the game (e.g. to evoke emotions or establish moods). Thus these techniques carry the potential to move the design focus from pure graphics to game design and fun while playing.
The paper is outlined as follows: First it surveys the broad variety of graphical styles used in games and presents an overview of different visual perspectives. Modern games have departed from their primitive graphical roots and much too often, players notice that the game developer had put more emphasis on neat rendering techniques than on innovative game ideas. This will be shown by a historical comparison of the relation between gameplay and game graphics. Strictly speaking, no game developed so far can truly be called "photorealistic", but many games try to achieve "photorealism". Then we discuss the use of visual realism introducing the use of non-photorealistic graphics and its existing techniques applied in games. The paper concludes with a discussion of possible graphical styles in future games.

What Is Artistic Rendering (From Answers.com)
Rendering in visual art and technical drawing means the process of shading and texturing of an image, especially a realistic one. It can also be used to describe the quality of execution of that process.
The emphasis of the term is on the correct reproduction of light-and-shadow and the surface properties of the depicted objects, not on the emotional impact, composition, or other more generic qualities. Unsurprisingly, most often it is used in relation to the more exacting, meticulous techniques like pencil or airbrush.
In an artistic rendering visual information is interpreted by the artist and displayed accordingly using the chosen medium. The non-photorealistic rendering area of computer graphics develops tools and techniques to enable interpretive rendering in digital media.
