Before Nintendo and Super Mario Bros. took over there world, there was Atari and Mario Bros. Of course, Nintendo still made the original arcade game but it was popular on Atari (and other) systems of the time more so than the NES. It was of course released for the NES also but by the time the NES gained popularity, the original Super Mario Bros. had the far better Super Mario Bros. to contend with.
Like Super Mario Brothers, Mario Brothers also feature the Italian plumber duo, Mario and Luigi. Even the turtles and pipes will look familiar. However, whereas Super Mario Bros. was a side-scrolling game with many varied levels, the original Mario Bros. was played on a single screen at a time on levels that really didn’t vary all that much.
