Easily the best of Nintendo's arcade games. While Donkey Kong felt more like a game that should have been a console game originally, Mario Bros. and its more streamlined gameplay feels much more suited for the arcades. The game features a nice colorful cast of characters, including the introduction of Mario's green brother, Luigi. Turtles, crabs, flies, and icicles are found throughout the various sewers and all have different attritubes to make them stand out. While the movement is slippery, the game controls great and makes skillful play all the more satisfying after mastering the momentum. And the best part of all is that this can even be played with two players simultaneously. Fantastic game all around. However, I would suggest skipping the 2600 version.
