We now have a one new FIFA 17 gameplay video that you can watch to see how the the game plays. At Gamescom we see FIFA 17 gameplay for a full match with Marco Reus playing along with YouTube streamers.
EA earlier shared a new FIFA 17 gameplay video that is almost two minutes long, but it only shows a little bit of gameplay and not from an angle that you will actually play the game.
We should see more FIFA 17 gameplay later this summer. It's possible that some gamers played FIFA 17 at Gamescom and are waiting for the go ahead to publish the video.
