looks really good - a bit sad to see "Norway" rules all of the north... they were owned by Denmark once... of course.. they got those oilfields..
I think a gameboard shouldn't look to handdrawn as that might mess up ones ability to read it ... a very light blue could go into the oceans.
But one question does pop to mind though... 30-50 people - playing on the same board - thats a lot of people - sounds to me like the game would be spoiled by pure physical logistics - people going to and from the game board to make their moves (unless the board is huge - like those war-boards from WW2), and a LOT of waiting for ones turn... and damn to be the first one to loose the game and having to wait for the others to finish.. but very nice board.. and would love to hear more about the game
oh.. and have some rep for your fist upload
