If you like geocaching then I think you'll enjoy this game, as it incorporates exploration and photography of historic and cultural sites like the ones indicated on the maps here. I am a member of the Enlightened (the green team), currently the local underdogs. If you would like to learn more, my email address is [tgbm dot ingress at gmail dot com]. Invitations are no longer required, however if you are willing to join the Enlightened, I have some available which will start you off with additional gear.

Bonus points if you're:
Unemployed
A cab driver
Insomniac
