I think I misunderstood the question. I meant that G40 had enough different unit types to cover the units in the game. But you are correct Empireman, pieces would need to be painted to have enough colors. Or, you could buy some other colored pieces. Playable powers are France, UK, Russia, Italy, Serbia, Germany, Austria-Hungary, Ottomans, Japan, USA, China, ANZAC. Serbia and China have no Air or Naval ability.
