Ever since his debut as Jumping Man back with the release of Donkey Kong back in 1981, Super Mario has established himself as the world's most popular video game mascot. Becoming known for his 2D platforming adventures, Mario has since expanded his collection of games to include everything from vast open world adventures, a whole host of sporting competitions and even the world of puzzling.
