I saw on many youtube videos of goal line technology in FIFA 15, but when playing, it never happened (and there were many chances). Can someone confirm that there is this feature in PC version? I'm playing in Italian Serie A, maybe this feature is disabled because in Serie A there isn't this technology?
Yes - it is in the PC version. I have seen 2 replays (one of which, the ball wasn't even close to the line) - and I've been playing mostly pro career mode (although I have done a fair bit of manager mode too - but not seen it here) over 150 hours. My player is currently playing in the EPL and that's when the replays occurred.
I think it may be more prevalent, but I usually skip replays (and goal line tech is not an instant review).
