I am among the first users of ingress in France, the concept feels good, but for the times being, there is not enough people playing to make it really interesting.
In my hometown (Tours,France) I think we are under ten people running the game for now, so I am the first who captured the portals in the center of the city. The game is addictive even though there is almost nobody, I can't wait to see more people playing.
There is not much portals for now, but you can submit your own portals. I think I will use the camera of my brand new Nexus 4 to do this.
