FIFA is a game you play co-operatively with your computer.
This is true of any game, of course; there is no play without the computer’s reaction to your inputs. But FIFA requires that you steer eleven footballers in real-time around a pitch you can see less than a third of at any given moment. To make that possible, you’re reliant on the computer to take hold of whoever you’re not directly controlling. You’re reliant on the game to correctly infer your intent as you wrestle with umpteen buttons and twin analogue sticks.
In the space between those two outcomes – intent and action – is where FIFA happens. Everything that’s good or bad about the game exists in that ambiguity. It’s why I love and hate FIFA 15 for all the same reasons I’ve loved and hated the last four iterations.
