Q: What influenced the design of foursquare?
A: Legend of Zelda was an inspiration.  You know how when you’re out on a mission and you find something like the boomerang, and you get totally psyched?  I loved that feeling when I was 8, and I loved it when I was 28.  So why not make a real-life challenge where an everyday serendipitous experience can feel like uncovering the boomerang in Zelda?

Encore une fois, l'importance des game mechanics dans le design thinking.
