If you are new to the game, whoever is better will win with either side. Usually one person has a very defensive personality, focusing more on not losing than pushing towards a goal. That will inevitably lead to defeat as the other person finds weaknesses and builds an income advantage.
It takes a large number of matches to have the natural Axis advantage manifest itself in face-to-face games. Don’t worry about the imbalance until you are able to predict what happens during the first six rounds of gameplay based just on the first round of dice rolls and spending. Fun game for both beginners and masters.
