Global is the best game
Calvin means the new 1940 game, which will be sold later this month. You have to buy Pacific 1940 and Europe 1940 ($60 each) to play the new global game. It will be the new gold standard.
Since November of 2008, the Anniversary edition was the game to play. It makes all other versions a joke. The global 1940 game will be much more involved, so as long as you have the time, or play online, then global 1940 will soon make Anniversary a joke.
So, as of the end of this month, all of us "pros" will be playing global 1940 and nothing else.
