I have to say that my first inclination was that the idea was a joke, and I thought that it was a funny one. Then I read the first post and it seems that the guy was serious, so I am not sure what to think. I am not doubting that companies are experimenting with the idea of what Pokemon Go! is with the immersion aspect, but I am not sure GTA would be the game to do it. Something about that just does not pass the smell test for me.
