The concept of beauty is often very personal. Beauty is in the eye of the watcher, even when we're talking about video games. A first-person 3D game could be a joy for the eyes of some gamer or a pain to others. Pixel graphics is often considered beautiful if the player grew up playing in a decade when games were almost entirely pixellated. Lots of old games are considered aesthetically pleasing even today: Another World is still a beautiful game to most of us, and so is true for Loom (those wonderfully colored backgrounds!) and many others.
