It's been 24 years since Mario first bounded across the Mushroom Kingdom in search of Princess Peach. Twenty-four years of platform perfection; of giddy, ebullient bopping. You know what they say, if it ain't broke and all that. And there is nothing or no-one in the video game sphere that stands the weathering of time quite like Nintendo's number one mascot. Nor, perhaps, is there anyone quite so versatile. When the 3D revolution came, Mario not only took it into his stride but leaped in headfirst, defining a generation with that same infectious joy. In that regard, the world may have changed, but Mario hasn't.
