In the gaming world, even if the game is good, the first selling point is going to be the graphics. Sure, there are the gamers that appreciate the gameplay first and the graphics later, but those games hardly ever get the widespread talk they need to get to make themselves known. It's always the flashy, good looking, eyecandy games that get all the attention. And sadly, pixel art isn't considered "flashy eyecandy" to the majority of gamers. They can't look at pixel art as we do here and appreciate the style, limitations, the technique it takes to work with pixel art. I think that pixel art is dying, at least in the gaming world, because the only reason people did dealt with it, is because it was all they had. Now that it seems 3d is taking over most of the gaming mediums, there is no need for 2d.
