Over the years, many of the Mario games have been very similar in gameplay style. With the Super Mario Bros. series, you explore side-scrolling worlds with various enemies and in each series gaining some new items or other gameplay style. The 3D Mario games like Super Mario 64 and Super Mario Sunshine involve collection of some object that will eventually help you finish your goal of saving Peach and these usually number to 120 (but not all are required to save Peach). So for most of the serie's life, it has had a similar history, and yet it is still one of Nintendo's most popular series. Even I'm tempted to go buy New Super Mario Bros. 2. But when does this end? The old saying goes "If it ain't broke, don't fix it" and Mario's lived up to this pretty well. But when does it become broken?
