Idea: Bleach: Brave Souls crossed with elements of Pokémon Go, i.e., walking or running IRL to get to the virtual enemies you need to battle (similar to running to Pokémon in Pokémon Go). Are there games like this, other than Pokémon Go, yet? If not, I'm waiting. *taps foot*
Other than this Bleach phone game Sean and I just picked up for the first time a few days ago, I very rarely play non-fitnessy video games, so I'm unfamiliar with what exists and all the pros and cons of AR, location-based games like Pokémon Go. I wouldn't want people to get run over or anything. With demand for fitness-related video games only increasing, however, there's definitely still unrealized potential here.
