Currently, my friend who's up with me in my vacation cabin downloaded it to his android phone on launch and let me borrow it for a bit to see how it works. Honestly, as I predicted it doesn't seem to be anything special. The idea of walking for Pokemon seems cool, but out here in this lame forest it doesn't even work well, and I don't mean the server issues in general, I mean simply getting a pokemon to appear. Both my friend and I have walked around the area for a good while and only two Pokemon have appeared, a Paras and Eevee. Both inside the Cabin, both only with incense. Zero Pokestops, Gyms or anything nearby, even though Niantic seemed to indicate there would be something for folks who are stuck in a secluded area. This of course means my friend is level 2 and stuck.
Overall, not really good impressions from either one of us, my friend being disappointed it wasn't like the trailer and because it isn't really doing anything in this area (even with 3G/Wifi access), and me being disappointed that the game doesn't even have anything to do if you don't live in a city. Hopefully they'll update with more stuff, but considering how they delayed the launch for the smaller regions who currently don't have the game, I feel that'll take a while. Still much better than Shuffle Mobile, though.
