WHY THIS DAY MATTERS
The soundtrack for Mario's games is some of the most memorable in gaming history. From classic tunes like 'Ground Theme' to more modern fare like 'Good Egg Galaxy', it's easy to find yourself humming along as you complete levels! Plus, there are all sorts of quirky sound effects like coin pickups and item collectibles that add an extra layer of delightfully crunchy audio goodness.
Mario has been around for over 30 years, and with each new game he just keeps getting better. His platforming gameplay is endlessly entertaining, featuring an abundance of obstacles, enemies and power ups to give fans hours upon hours of fun!
Not only are Mario games loads of fun to play, but they also have a vibrant visual style that makes them pleasing to the eye. From the iconic 8-bit art style of the original titles to the more modern 3D rendered graphics of recent games, it's hard not to be impressed by how great these games look.
