Now a days whenever you hear the word network you may think more about social networks than railroads and power lines. But board games tend to be a little bit more old fashion so you're likely to be a rail baron than a blogger when you sit down to the latest hot game (at least I don't think there are any games about social networking yet). So get your conductor's hat on, or whatever rail barons wear, and get ready to build a network to span the globe. Oh, we can't build railroads under water yet? Never mind, let's leave the globe spanning to the social networkers after all.
