If you play today's massively multiplayer online role-playing games — World of Warcraft or Final Fantasy, for example — you have a 1970s tabletop game to thank, says author Michael Witwer.

Secretary of State John Kerry stepped before a packed auditorium Thursday. He was at Indiana University for the opening of a school of international studies.
