I feel like the Alpha +2 changes have balanced the game more than enough – these additional changes are unbalancing.
First of all, I’ve yet to see a +2 game where an Europe or Pacific-only strategy pays off for the US. If the US weren’t in the game at all, the Axis would have no trouble getting their victory cities on either side – given that victory can come from one theater for the Axis, the US has to balance their forces or they will lose the game. In fact, it takes the Allies walking a very fine line to avoid losing the victory city game in alpha +2.
Secondly, if you’re looking for a balanced game like the Anniversary, you might as well take G40 back to the store, because there is no variation of 1940 that will capture that same symetrical balance. In Anniversary, the incomes and armies become relatively even after the third round or so. Then it all comes down to tactics and rolls of the dice. Global 1940 may seem extremely unbalanced (and it certainly is in Anniversary terms), but only if you ignore the massive tactical advantage the Axis have. With every roll of the dice and every unexpected move by your opponent, you will need to adjust your strategy – the Axis can pick their battle and have the mobile forces to quickly change strategy, whereas the Allies are either stuck pumping out slow infantry walls or stuck behind oceans.
In every game of Global 1940 I’ve played, OOB or Alpha +2, the game was won or lost by the Axis. The Big Book of Allied Defense is already written – the moves you need to make are known. When the Allies win, it’s been because the Axis wasn’t aggressive enough in the beginning or they got too cocky and attempted a low-odds battle. When the Axis win, it’s because their opening moves put them in position to take on the superior income of the Allies.
Finally, it’s worth mentioning that a lot of people that complained about Axis inferiority in G40 also played a lot of the earlier editions. I’ve looked through some of the Axis overall strategies for those editions, and they are way too conservative to work in the new game. I sometimes wonder if some of the Axis players aren’t able to look past their favorite strategies for the previous games.
