Graphics and good art ARE a large part of entertainment for most people. I accept it and I do appreciate good graphics and art. I know that gameplay is very important to keep the a game viable to a large market; but so are graphics and art.
The gameplay and graphics together make a game stronger than just one alone.
Other forms of entertainment apply also. Movies, for example, are often more popular("better" is really a term of opinion applied to popularity)if they have both good acting AND settings/visuals/graphics.
