Another option in a 2v2 live game is to split the Allies up by theater, which we like to do.
Allies player 1: US (Atlantic), UK (London), Russia, France
Allies player 2: US (Pacific), UK (Calcutta), Anzac, China
Ofcourse this involves heavy coordination in strategy of spending US $. It’s give and take.
We have done this in the past, and it is pretty cool. The 2 US players lobbying for income/units is kinda what happened historically (which theater gets a boost?). Does the Pac player allow the Siberians to march home? Dose India give up some air/fleet to Egypt? This gives the Euro and Pac allied players something to do throughout the game, and coordination is a must. Some of their powers are in the fight from the get go, some are dwindling, and others are ramping up.
On the Pac side, US controlling Anzac seems right because they need to work together once the US gets into the game. As China/India looses ground the US picks up steam so that player is involved throughout.
On the Euro side the UK gets a lot of action as do the French (turn one). The US/Russia comes into play slowly, and you don’t want someone to have only the US/Russia because of that.
In our group Russia is an inept power to play because it can be very boring unless there is a Sea lion. There is nothing good about playing the US/Russia, waiting for 3 rounds to go by, and the game is paused until the next day lol. Even when we split the allies up differently, Russia is a bit of a question. Sometimes we alternate Russia’s turn between both allied players.
