My favorite system of all time is the Atari 2600, and you would be hard pressed to find a game made for it that had any sort of story in it, besides those based on pre-existing stories, such as movies or something similar. Two of my favorite games of all time are Space Invaders and Pac-Man, and these have little to no story. Perhaps today people think these games are repetitive and dull, but I still like them. But most of the modern games need stories, with some exceptions.
