Gaming is a huge market, and if you go in to any free to play game it's absolutely inundated with kids/preteens.
You can also roam using apps that let you do Google street view stuff in VR, create art, watch movies in a theater like experience alone or by yourself, and of course a lot of people use it for porn.
Even usual non-gamers love stuff like Walkabout Mini Golf or Star Wars Pinball.
