I hate lists like this. Pac-man? Tetris? Asteroids? Sure, they're good gimes, but are the the best videogames of all time? No. Can you sit and play them for hours, days and weeks at a time and still gain enjoyment out of it? No. Just because they were revolutionary at the time, doesn't make them the best of all time. The Beatles helped revolutionise music, but it doesn't make them any good!
