In an interview promoting Nintendo's upcoming game Super Mario Maker, video game designer Takashi Tezuka reveals that all of the original Super Mario maps were designed on graph paper.
"Back in the day, we had to create everything by hand. To design courses, we would actually draw them one at a time on to these sheets of graph paper. We'd then hand our drawings to the programmers, who would code them into a build."
It warms my heart to know that one of the most successful video-game series of all time wasn't designed using a sophisticated custom built platform, but with good old-fashioned pen and paper. There's hope for us all yet!
