A completely updated version of the popular Medieval Realms Castles Game, in which students design their own castle and by so doing learn all about the key features of castle design. New additions to this game include factual questions as the story proceeds, so that the students are given two scores at the end: one for the quality of their design, and one for the quality of their factual knowledge. Another new facility allows students to submit their scores to their teacher via email: these will be collated and sent as one email rather than as separate messages for ease of transfer into a markbook.
