Im not that excited about the 2nd generation as I still have 20 to catch from first gen.
With the gym thing, it does get a bit serious. Talk of facebook groups to alert people to go out and defend gyms which are being attacked, etc it is afterall only a game.
I am quite glad the local gyms were taken out they were level 10 for weeks and couldnt get near them and now they change all the time again. People will just stop playing if they cant get a gym anymore which is not what niantic want.
