Here are my first impressions on the demo:
Defence AI is fixed
This was a thing of beauty. Coming down on the wing and trying the old, defence fuckery, only to have the defence *gasp* skate backwards and move their stick back and forth to disrupt the play. They didn't come and challenge, they played their spot. CPU uses a lot more stick waggle this year, and it actually makes it a challenge to play. I was playing pro and All Star, and each game felt really challenging like I wasn't just getting a win. I didn't win actually which was nice.
With this as well takes away the cross crease a lot, as defence are playing properly, and it seems so far that Def AWAR means something. Better defencemen make better plays. I tried a bunch of times to do a cross crease, and they were not getting through. My final gola in OT, I did a semi one, as Chara went to hit Sedin and he put it in, but that was 1 for like 20 tries.
AI is just so amazingly improved in this game I can't get over it. Some many exploits are gone from the game (until they are found) because the AI is actually doing the job. Even when you have the puck at the point, they don't sit there on a post and wait. They come up and make a play on you more.
Demo is slow
The tempo seemed really slow to me compared to NHL11. I'm debating if I like it or not, but this is probably something you just get use to considerng just 7 hours ago I was playing NHL11.
Checking is...something
One of the first big hits I blew up Horton and it looked really WTF? I also noticed when you hit people they seem to fall forward for some reason and not back. But it does look like size might matter, as this year I wasn't blowing guys up on the boards with regular players and it was a more fluid hit hockey should be. Some of the big hits look a little wonky, but it isn't a deal breaker for me, as hits on the boards look good. Though one thing that worries me is I just bumped Krecji near the bench and he went right over.
Net play is there
I was swinging the puck at the point all my guys were in front battling for position. Put the puck on net and picked up a fat rebound for my goal. It actually looks like it was done right this year.
Shooting and rebounds
Shooting seems better. It isn't these rocket shots, but looks fluid and more real then last year. Also rebounds actually bounce, they don't just come out onto the stick. I took a slap from the left dot, it went to the right and bounced off the ice.
