The thoughtfulness of Retro Bowl's difficulty curve is more evidence of its quality. Beginners may have a good time getting the hang of the game from the start because of how simple it is to pick up and play. However, the challenge increases in small but discernible increments throughout the game. With the improvement of opposition defenders and the harsher punishment for mistakes, maintaining a successful squad is becoming more difficult. The game never feels harsh, but it does force you to improve your decision-making and execution.
