Here is a screenshot from the game. It is at zoom level 5 of 6 looking at the political map of the German / Polish border right before the invasion.
















Here is a quick summary of my game:

• This is a grand strategy level game. Units represent Corps and Armies, Naval Task Forces and Air Fleets. Players will be in charge of research, production, diplomacy and troop movement.
  
• The game map covers the entire world in an equirectangular projection from just north of the USSR to the southern tip of South America. Every country that fought in the war will be represented.
  
• The map consists of 400,000 cells (1,000 wide x 400 high).
  
• The game uses a simultaneous movement system. Each player enters orders for all of his units and then the turn is resolved simultaneously. Then each player can playback the results as many times as they want before begining the next turn.
• Fog of war will be implemented.
• I plan on implementing a learning AI that should adapt to player strategies.
