BoardGameGeek (BGG) is an online forum for board gaming hobbyists and a game database that holds reviews, images and videos for over 101,000 different tabletop games, including European-style board games, wargames, and card games. There is also an annual Spring BGG.
In a project funded by the German Federal Foreign Office, Industrial Design students at the University of Wuppertal designed board games to foster pupils' interest in foreign policy. All games are open source and freely available as print-and-play PDFs.
