What changed in fifa 15?

i can't say i have been waiting for this game but when it came out....i went to play it at an exhibition shop. i have fifa 14 on my pc and have been researching about fifa 15.....these were the changes i was told about:

1) new player emotions......i didn't see it once after playing 20 ******* matches

2) a better gameplay.....after the average gameplay of 14, i did not see one single change in that department....

3) better graphics......the field looks brighter but not better....the menu looks awesome but 14 was better.....the players look just as elastic as 13 and 14......the animation of player faces was pathetic.....

4) A genuine footballing experience.....i am sorry but i didn't feel it once....

so why the **** did it still make so much sales?.... i know that this is based on my opinion but i kbow that what i have said is very much true.. .

so please explain to me why one would spend money on a game that changes every 3 editions???

should pes just be considered the best now?

would you spend 100 pounds on two games that are exactly the same?
