NHL 15 PS3 or should I say NHL14

Why have I been had by EA? I bought NHL 15 for the PS3 as I have bought many of the other installments to this franchise, but was utterly digusted with the fact that EA would allow the following terrible act. EA Sports NHL 15 was virtually copied and pasted from NHL 14, the minor tweaks to the game are useless, new announcers (that are annoying), a new cover (so what), a roster update (of course), and some "real physics" (who are you kidding?). The gameplay is exactly the same, as are all of the menu's. I wasted so much money on this game! I really hope I can just get my money back and move on with it to be honest! I even tried out the game on PS4 before I bought it, thinking "WOW, this is a great game, I'm sold on getting it for myself for my PS3". What a mistake, but the greater mistake was made by EA for even allowing this game to go ahead and see the light of day. All I ask for from EA is an apology for the idiotic act of releasing the same game under two different names and a full refund!
