1) Successful marketing campaigns use play to build relationships between brands and consumers by providing playful experiences. This aims to convert players into buyers by positioning the brand.
2) Engagement is increased when consumers participate in something they identify with, like Adidas' campaign for the 2012 Olympics encouraging people in the UK to showcase their talents.
3) Creating communities around a shared interest, like CrossFit partnering with Reebok to establish fitness boxes, facilitates social interaction between players and brands they have in common.
