With the tagline “The world is not what it seem” ~ .. and boom .
I got started with ingress game about early July 2013.

Eventually I got new friends and move around a lot too, I managed to get to L8
by the end of August or somewhere around that timeline.

Well, it is addictive, as using real world map as the game map. 😛

And for me , yes, its replace my foursquare check in time even if not completely.
