In this latest FIFA 15 trailer it shows how goalkeepers have been configured so that they react individually to different situations. In the old iterations goalkeepers would perform the same function in different situations because the hardware wasn’t powerful enough to accommodate the minutiae of different sscenarios. For example, a goalkeeper would punch the ball away rather than catch it in a host of situations where a real goalkeeper would have acted differently. Therefore, FIFA updated the goalkeepers AI so they act as a real goalkeeper would rather than as a preprogrammed bot.
*Disclaimer this update and many more like it in FIFA 15 only apply to the next-gen consoles. The older consoles aren’t powerful enough.
