Kylie and Kendall Jenner are following in big sister Kim Kardashian ‘s mobile game success by working on an app of their own. The sisters, who rose to fame on the popular reality TV show Keeping Up with the Kardashians , are working with Glu Mobile to build a mobile game that features the “voices, likenesses and creative influences of Kendall and Kylie.” While Kim Kardashian: Hollywood game focused on becoming famous in a virtual world (and even featured character cameos from Kendall and Kylie), the Jenner sisters’ game will center on interactions with others and mentors as they grow their careers.
