Night Walk is a Google-sponsored (and probably developed) experience using Google Maps Street View, audio clips, and video/photography to create a digital “guided tour” of Marseilles, France. You click and pan to follow a preset route, discovering hotspots that provide information on local sights, and you can go off-course and follow some side paths.
While there isn’t a real game here, it’s a fun website and a cool use of the Google Maps API. And as someone who does work on the web, I can appreciate how difficult it is to get API-driven systems to work seamlessly without lots of problems. Google Earth VR is another cool use of Google’s huge amount of map and photographic data, and there are some similarities between the two.
