This week's Dev test game was North America, the map David has just finished. (Well, almost finished, the units for Mexico and Central America still to go...) This is one of the handful of 'big' maps that will come with SR2010 - hundreds of hexes wide, 25 km to the hex. In other words, big. In fact, this is the size of theatre that just can't be done with most other strategy/wargames, whether they be games such as the Civilization series or more traditional wargames.
To some extent, a game map this large doesn't make for the best multiplayer games, at least not one that you want to finish in a single sitting. Two of the players, 'Canada' and 'US West', have regions so large that they are hard to monitor and manage in real-time mode. For many players, this will be a good type of map to play over time in turn-based mode.
In the end, Mexico/Central America made a good showing, using cheap labour to build up a Military infrastructure from scratch, and used the 'but it's only Mexico' sympathy ploy to trade for the best technologies from the other regions, eventually launching a Tomahawk attack on Florida. There was a 'Hunt for Red October' type chase as two of Mexico's aircraft carriers (purchased from the US West) made a daring raid and then escaped back to home waters. But in the end, a web of intertwined alliances and attacks had everyone at war, and the large land and air forces of US West and US NorthEast dominated. It was called a draw between those players after over 6 hours of play.
