In the season mode, the game will even let you set the sim length of a game. That is, if you play with 5 minute quarters, you won't get accurate stats. While your team may score 40 points, the rest of the league will score plenty more. To even it out, you can adjust the sim quarter length. By setting it equal to the length of your quarters, all teams are on an even level.
Scores are similar league wide, and the statistical categories are also more equal.
This is no sim. In fact, if you were to compare it to another one of EA's games, I'd say FIFA would be an excellent comparison. FIFA claims to be a soccer simulation, and much of the gaming public blindly agrees. But the more you watch real soccer, you realize FIFA is nothing more than an arcade footy game wrapped in simulation clothing. FIFA lacks so many elements of real soccer that you simply can't call it a simulation.
