Any videos of the impact engine? Proper in game video, not the trailer.
Did you find players get tackled more? Did it slow down the pace of the game? I could see that being a problem.
What about tall/strong players vs weaker players. Does this come into effect? I've seen Messi shoulder barge his way through defenders like Richards and Kompany.
No gameplay vids yet, weren't allowed to record! Umm tackling is a totally different game. It requires perfect timing and positioning. Basically you press A to 'contain' which is ensentially the same as holdingnleft trigger in 11. This causes your player to jockey the player, and then you press B to go in for the tackle. It's much better than just holding A as in 11.
Player characteristics seem to be improved. Especially with the impact engine, messi won't be able to overpower bigger players, if he try he will just eat the dirt.
Generally the gameplay speed has slowed down but in a good way. With the new tackling you get more time on the ball, and have to really work to make space.
12 is so much better than 11, but still not perfect but debs assured us it will be much more polished.
