I don't think I've played Pokemon GO in like 2 or 3 weeks now. I want to play it, but there's nothing to keep me going. Yeah, I haven't filled up the Pokedex, but I have nowhere to go, especially since my car broke down recently. The place I live only has like a million Pidgy's, half a million Weedles, a couple Eevees, a handful of Bellsprouts, and sometimes other misc. Pokemon if you're lucky. It doesn't give people who live in rural areas anything to work with. Maybe once gen 2 Pokemon come out, I'll play it again, because maybe they'll fix some of the problems.
Though, maybe not because they're adding trading soon and that'll kill the game because then no one will be motivated to go out and catch Pokemon. People will just sit around and trade high level Pokemon and the whole reason for the game will be lost.
