Let's be honest, there's nothing much I can say about this game that hasn't been said by everyone else, so let's just point out the obvious and make this really quick: "Super Mario Bros." is still a fantastic game that's fun, challenging, well-designed, and all-around excellent. There's really nothing to say other than that it's stood the test of time and, to this day, it remains a highly influential game that you absolutely must play.
Final rating: 10 out of 10 "Fantastic"
