Why does everything (in big-budget video games) look shiny and wet? If it is an attempt at realism, reality is not constantly shiny and wet. If it a subjective artistic choice, it is objectively wrong and ugly. Is there an expectation that everything look shiny and wet to make it seem more "dynamic"? Is it an artists' meme, like the Wilhelm Scream in cinematic sound design?
"Mann sprayed down the city’s nocturnal streets with tens of thousands of gallons of water, so that they took on an unreal, painterly glow." - New York Times
