Ingress is Augmented Reality game developed by Niantic Labs (http://www.nianticlabs.com/) with over 10 million player base across the world. As a committed (I avoid using the word addictive) player for more than 2 years, I would say the two best things about ingress are,
1. It is a real-life game - You have to travel, walk, ride, drive to play Ingress - this game takes you to places otherwise you would ever think of going.
2. It is a community game - If you are a higher-level committed player like me, you would have 100s of buddies in every city you travel - whenever I step into a strange country, A ingress buddy is the first person to greet me

I have been playing for years and I still love it. Enlightened players. Check in on Swarm. Look for "Playing Ingress Enlightened" when checking in.
