Saw the post on geocaching and thought I'd ask how many currently play ingress. It's a massively multiplayer location based game. Sort of like capture the flag meets geocaching.
They hold large events in cities all over the world with a large live event planned for Calgary in June. Im a relative noob in the game but have enjoyed it... Done geocaching with the kids but now ingress as well.
