As mentioned in a prior InsideGMT post, Jon Carter, of CoV Transatlantic Team Playtest Team fame*, created a version of the game, from Terry Leeds’ graphic files, for bringing Congress of Vienna to SDHistCon in San Diego. In recognition of a four-hour time limit per play session, Jon chose to present the three turn Desperate Times: The Campaign of France 1814 scenario. For more regarding this scenario, with links to additional Congress of Vienna material, see: Congress of Vienna Scenario Set-Up Maps with Associated Historical Backgrounds | Inside GMT blog
Below is a copy of the email Jon provided Game Designer Frank Esparrago and Assistant Designer/Editor Fred Schachter, with some excellent photographs, of Congress of Vienna at SDHisCon.
