I've been reading this strange but fun sci-fi book by this Russian author Dan Sugralinov, about a man who's a loser/game addict who then wakes up with a mysterious implant in his brain that lets him see "stats" of people, and connects him to some mysterious network of information. "Restart" is the name of the first book. Not only does he see people's stats and standing in the world in the form of social level, but he becomes obsessed with upgrading his own stats, as if he were living an RPG game itself.
