From a game design perspective, PokeGo and it's predecessor Ingress, is quite unsatisfying. This is by design in an attempt to keep people playing. Game design by engagement statistics.
There are people complaining about the tediousness of actually traveling to locations to play the game. Silly people. The PokeMon GameBoy version has been around since 1996.
I think this is just a fad and people will move back to non-ARG games.
For us cyclists, Strava is the equivalent ARG. In my opinion, this is the correct application of this idea. At the same time, things like Zwift is interesting moving people to VR.
