Nah, you guys who haven't played the game yet really need to ignore the ones saying it's the same as previous years.
As someone who spends 250+ hours on the NHL games literally every single year they've released, this is most definitely the most drastically changed game from one year to the next since I started playing back in 2008.
The number one change is skating, which is almost a night and day difference from last year to this year. The difference in speed between the faster smaller guys and the bigger slower guys is extremely noticeable. And while in previous years this would be a bad thing because it would mean the small skilled guys would dominate game play, but in this years game that's not the case. The physics engine tweaks have had a big effect as well. Hitting is much more realistic and more effective this year, as the small little checks in tight that in previous years would have no effect on a player, actually has an effect this year. It can slow down the faster guys, it can knock the pucks of the stick more often, and causes separation between player and puck much more smoothly now. Hitting is no longer a simple matter of either it works and fully removed the receiving player from the play, or it didn't work at all and removed the player attempting the hit out of the play.
The long story short is this game is massively different form last years. Mostly in a good way as well. Skating, hitting, shooting, goaltending... It's all improved. Not perfect by any means(And it never will be), but it feels like an actual hockey simulation game this year. Significantly less of an arcade feel then the previous years.
I really cant speak enough for how much better the skating is. You just have to go and play with it yourself and see all the little changes that were made to really get a feel at how smooth and how improved it is compared to last year.
