If you have played Mario games before, then this shouldn't be a foreign concept. The goal is to reach the end of the level. But the path to the finish line is filled with obstacles, enemies, and other paths to discover. Ever since Super Mario Bros. was released for the Nintendo Entertainment System, the formula has seen improvements and additions that made the experience familiar, but with enough elements to keep it both challenging and fresh. New Super Mario Bros. Wii pays tribute to these games by borrowing many of the elements seen in past games, such as the red coin challenge from Super Mario World 2: Yoshi's Island, the ability to store items from Super Mario Bros. 3, being able to pick up items and enemies from Super Mario Bros. 2, and even the classic Mario Bros. Arcade game sees representation in the form of POW blocks.
