On September 13, 1985, the Super Mario Bros game first appeared.
An excerpt from the article:
"On September 13, 1985 in Japan, Nintendo released one of its most iconic games ever, Super Mario Bros. Designed by Shigeru Miyamoto and Takashi Tezuka, it was a smash at home and became the Nintendo Entertainment System’s killer app a year later. The world was never the same.
As Famitsu points out, the game became synonymous with side-scrolling action and would influence countless game that followed.
Before Mario, there were iconic gaming characters, most famously Pac-Man. But it’s the red-hat-wearing, mustachioed character’s continued string of excellent games and endearing qualities that make him stand out like no other."
