Any thoughts on setting? Personally, I think it would be better to go with something familiar to start, contemporary Canada or the United Kingdom being the two most obvious choices; anything too exotic and we risk going the way of the South America game and spending more time researching the scenario than actually playing. Once things get off the ground, we could then experiment with more creative scenarios if we wanted (a federal Europe or British Republic being two possibilities).
