In an interview with reporters, the executive producer of the project, Aaron McHardy, explained that this decision was made due to the company's desire to keep the game's system requirements at the same level.
Executive producer Aaron McHardy said:
“When we looked at what generation to put the PC game on, we looked at our fans and what capabilities they had with the hardware they have.
And we have that information to understand what the power of the PCs out there in the world are. And when we looked at that, in order to run the gen five game, our min spec would have been at a spot that would have left a lot of people out in the cold not being able to play the game.
So we made the choice to keep the PC version of the game on the gen four version of FIFA so that we can open the doors and be inclusive to everybody who wants to play FIFA.”
As a result of this research, EA concluded that if new technologies are used, the game's system requirements will jump so much that a large part of gamers will not be able to run the game even at the minimum specifications. That is why the Americans refused to release a football simulator on the PC that matches what was created for the PlayStation 5 and Xbox Series S/X.
