When we play A&A G40 at my bunker it’s always with 6 players, and we play a fast game due to our unique turn system that has worked quite well for us.
Here’s how it works…
In a 6 player game…
1. Simultaneously the German player begins their purchase new units phase, the Russian player moves their eastern forces (18 infantry and 2 AA guns), and the Japanese player begins their purchase new units phase.
2. Simultaneously the German player ends their collect income phase, the Russian player begins their purchase new units phase, and the Japanese player begins their resolve combat phase and/or non combat movement phase.
3. Simultaneously the Russian player ends their collect income phase, the Japanese player ends their collect income phase, and the American player begins their purchase new units phase.
4. Simultaneously the American player ends their collect income phase, the Chinese player begins their purchase new units phase, and the British player (Europe) begins their purchase new units phase.
5. Simultaneously the Chinese player ends their collect income phase, the British player (Pacific) begins their purchase new units phase, and the ANZAC player moves their forces in Africa (2 infantry).
6. Simultaneously the British player (Europe & Pacific) end their collect income phase, the Italian player begins their purchase new units phase, and the ANZAC player begins their purchase new units phase.
7. Simultaneously the Italian player ends their collect income phase, the ANZAC player ends their collect income phase, and the French player conducts their entire turn.
8. Repeat…
PS: We have found that Japan is the real clock pig of all the nations. The player playing Japan should always be starting their purchase new units phase when Germany does, and they should always be ending their collect income phase when Russia does (or shortly after). This one little trick will save you at least 3 hours every game.
