I’ve always wanted to do something like this and it looks like Nike did it in Bangkok. it’s basically a real life Pac Man game for runners. This is a great idea on so many levels. It motivates people and brings them together through social gamification and it’s a great way to both market a product – running shoes, and encourage people to get outside and get some exercise. They also integrated the game into a widely used messaging app so no additional downloading was necessary. Nice work!
