Add emotions to the players of both teams
Real understanding of football is one of the things that can turn the experience of playing with a sports simulator upside down. That's why EA Canada has done its best to create a real emulator. An attempt to make the gamer feel like watching a real football game on a TV screen, not a computer game. That's why every player now has his own emotional system for everything that will be reflected in their morals and appearance.

Advanced defense system
Another notable change in this version is the change in the opposing team's defense system and tactics at critical times. For example, if you play an important game in the final minutes and need a goal to win or draw, the opposing team will try to stop you from achieving your goal with a defensive tactic of 11 players. Conversely, there is also their all-out attack when you are winning the game.

Better modeling of players
Another breakthrough in FIFA 15 is the better modeling of players, thanks to EA's efforts, this time instead of the shapeless bodies of FIFA 14 with shaved and more proportionate bodies that are similar to the real limbs of digital players. More professional simulation and modeling has been done, especially in the shoulders and chest muscles of the players, and thus, we will see more visible and believable muscles in the players.
