As of Thursday morning I own the Moscone Center. The Mashable office in San Francisco is also mine, as well as a a pretty popular bar across the street from my apartment. Tonight I have my sights set on picking up AT&T Park.
All these acquisitions are part of a new game called Turf. Think of it as Monopoly set on top of Foursquare. The game allows you to buy up property in your neighborhood, purchase add-ons such as additional floors, and earn virtual rewards in the process.
