The "scripting part" actually was pre-programmed in every aspects of game mechanics. It is in every fiber of the game at any given minute of the game.
1/ The ball physics, collision, trajectory, player momentum does not only follow the rule of real world physics as a simulation. That rule can be changed almost always to obey another ultimate law of the game:
The Ultimate Rule Of Punishing The Player:
Handicap and disadvantage the players so that he always has to on his toes to a masochistic level. The game finds pleasure in frustrating the player, be it obnoxious, annoying, incessant pressure from computer AI
or the unexplainable behaviour of your AI team mates.
This is the first football game in which the ball has its own AI programmed to play favorite the whole match either in impossibly STUBBORNLY REPEATEDLY bouncing back to an opponent feet regardless of your skill of tackling or persistently magnetized to an invincible god-like opponent feet.
The ball physics and behavior is also synchronized with opponent position to dispossess the player or to take control away from him. Your first touch suddenly becomes impossibly bad for no reason at all ( even after receive a well-placed and soft pass) which resulted in the ball drifting impossibly away from You or bouncing uncontrollably whenever there was a convenient opponent nearby.
There is a universal law of ball behavior in this game: drifting ball, deflected ball. bounced off ball, loosed ball will always be directed to/locked on to opponent running path.
In long passes, the ball running speed will suddenly slow down or speed up in perfect timing to be intercepted by your opponent regardless of your timing, strength of pass and intention, your passing skill does not factor. You find yourself asking the ball a lot of questions about the way it disobeyed You.
This is the game of the perfect invisible grid in which the ball and your opponent are mutually locked into each other at all time, while You were trying to run between them in vain like a headless chicken on a pre-determined rail. Do You have any chance at all?
2/ To further this masochistic and malicious ruse, the player input is severely interfered with to his disadvantage. Player never has real control to his avatars in the game. They are programmed to disobeyed the controls.
There is always delay, dazed, running away from the ball after a tackle. The cursor switched suddenly to another player at the most crucial moment for no apparent reason when it needs to focus on your controlled player the most.
3/ Pre-determined lock-in mechanics event , in which player has no input in anything:
Your player always keep delayed by being obstructed by the body of a falling opponent after your successful timing tackle.
After a successful tackle, instead of continuing running towards the loose ball, your player is dazed, confused, the cursor suddenly taken off him.
There is always a perceivable pre-programmed distance between your defenders and the opponent strikers with perfect timing so as he can always have plenty of time to evade your tackling as you approached him.
In these impossible and desperate moments, the sliding tackle will certainly earn you an instant yellow card.
Your player always run on rail slowly along side the opponent striker, then neatly tucked in behind him like ducklings follow their mother, regardless of your bust-a-gut running direction changing effort and speed.
The game is full of such annoying unjustifiable locked-in-place micro-events like that, it is so easy to see the scripting and handicapping.
Sometimes playing the game makes me feel like I just watching a GIF Animation played over and over again at numerous predetermined moments.
In fact, the game is nothing but a series of gif animations to create a hallucination that You are in control, but the gif animation will never change.
