In reply to Adrien:
I remember the old Pokémon games for the GameBoy Advance. I played some of them on an emulator, way-back. They were pretty cool because of the mathematics behind the battles and the exploratory nature of the game. Can't say that Pokémon Go calls my name - it seems geared for micro-payments and viral-ness and the only battling seems to be poorly thought out and biased towards either pay-to-win or players who have infinite time.
I have nothing against it, though, although I think it will lead to a huge rise in "distracted walking" - something I do have a massive problem with, as a cyclist and motorist and pedestrian.
Hopefully, it proves to be a gateway drug to "being out and about" and not just a gateway drug to "more Pokémon"
