World of Fourcraft is Like Real-Life Risk, Played in New YorkS

Foursquare, the hot social network expansion that ... does ... social things ... yeah, actually, that's sort of the problem. Sensing an opportunity to make the "check-in" utility for Twitter "more compelling for long-term use," some people have used it to turn New York into a giant game of Risk.

Foursquare, if you don't use it, employs GPS-enabled smartphones to check you in at places like bars and restaurants. What World of Fourcraft does is invite users to pick a faction (the five boroughs), and then checking in somewhere else in New York amounts to putting a plastic soldier on the map in Risk. An algorithm then determines which faction controls the area.

Right now World of Fourcraft, built by a seven person team, has about 100 players. Mashable spoke to one of the developers, who said he's thinking about adding a leveling mechanism that makes power users' check-ins count more toward claiming territory for their faction.
