Probably not. Niantec's previous augmented reality game, Ingress, was not even close to as popular, despite having most of the same gameplay characteristics. Working with the Pokemon franchise was a brilliant move.
The reason it worked is because Pokemon itself is about traveling to different places and finding rare pokemons. That's literally the app - there is 100% congruence.
I think it also helps that Pokemon GO simplified the experience from Ingress which makes it more accessible to a wider variety of people.
