"The experience reskins an actual location in the fantasy environment of Berk, the island in DreamWorks' How to Train Your Dragon 2 animated movie. You can explore fantasy-style landscapes - layered on a map of San Francisco - while flying around on the back of a creature like Toothless, the Night Fury dragon from the film. This kind of app is a hybrid of exploration and actual gameplay, and it is an interesting experiment that blends different mobile technologies as well as movies, games, and the real world. "
