I've just had this ping this morning, 50 hours doesn't seem that long but you'll have to play a lot of games to do it.
In order for it to ping, I've got basically every achievement bar the clubs long term ones, and 500 with my pro (I'm just over 200).
So 100+ ranked matches (12 minutes), plus all the grounds and different leagues, plus 2 and a half seasons in career mode. (8 minutes, as I play on shortest time allowed)
Based on the games I'd played I calculated that I was on about 48.5 hours, so injury/extra time is obviously counted as well.
Also, as said earlier all games must be played on your own console.
