I like more interactivity, like what you achieve with a physics engine, over improved graphics. But the main concern is about how the game changes in difficulty, to make something that continually stays challenging and never becomes impossible or extremely easy. Sometimes ranked multi-player systems achieve this, but i would like to see more single player games that do not have set difficulty caps, but a changing difficulty based on your performance.
