Just to follow-up on Rhineland’s post, typically Allied strategies trail the Axis. The Allies need much more cooperation then the Axis in the vast majority of games, but once an Allied player perfects this they become very tough to beat and bids are required. Now I’m not sure how these games are play tested but having it tested in a 5 player scenerio is much different then testing it when there are only 2 players.
Some major disadvantages are:
1 - 3 vs. 2, with economic lead by the three Allies.
2 - Russia goes first.
Here they can attack and replenish supplies before Germany can go.
3 - Poor dice hurt the Axis more than the Allies.
If Russia gets poor dice, the UK and US can reinforce with troops almost immediately, if Germany gets poor dice it is not that easy for Japan to help quickly. Kill Germany First effect.
4 - It is cheaper to defend.
B/c the Allies start with the economic lead the longer the game goes the better it is for the Allies. So the Axis MUST attack and must attack early to change this. But the most effective unit in the game is infantry. For the price of one inf (3 ipc), the attacker would need minimally 1 inf, 1 rt (7 ipc). Now realistically you have units on the board and it actually works out to the attacker needing to spend 4 ipcs for every 3 ipc spent on defense once you get to stacks of about 10 units. So if Russia has a stack of 20 inf (60 ipc), Germany needs to have 80 ipcs worth of attacking units. Again this is a big difference that must be made up early on before the UK and US get up and running. Any delay in Germany adding to its IPC count helps the Allies even if they come out on the short end of the battle. This boils down to the Allies can do nothing until they have overwhelming odds in a battle, the Axis MUST make aggressive moves earlly where odds may be in the 60-70% range (sometimes lower when you consider all the battles together for one turn).
For Example, if Germany has to do 5 battles, and all are 90% to win, the odds of winning ALL of them is only 60%. (.9*.9*.9*.9*.9 = .59)
So now mix in one or two 80% battles and a 75% and all of a sudden a turn that looks like this:
.9 * .9 * .9 *.8 *.75 =
Turns out like this: 43%
The Allies can pretty much pick their spots and wait (in no bid scenerio).
