Gamify ecommerce : by combining Google maps with digital storefronts, better than the interface they have now. Make it more like the Oasis in RP1 (Ready Player 1) where people can walk around in a digital world where your avatar can actually walk into these stores, and order. (e.g. I can log in and either walk or fast travel to Marconis and order in game. Then I can either have it delivered or pick it up myself. This can be done already either online or by phone, but those methods aren't as interactive.)
