List of Other Augmented Reality GPS Games inspired by Ingress
Ingress was not the first of it's kind, but it was definitely the first most successful (I think)!
What other games do you consider to be similar to Ingress (that you really have to go OUTSIDE and play), that you suggest and like to play?
Here are some that I know of:
PokemonGo (you probably never heard about this one =D )
The Walking Dead: Our World
Jurassic World: Alive
(Still in beta:)
Delta T (deceased, unfortunately)
