According to IGN's preview, NHL 2K11 is one of the few quality sports simulations on the Wii this year.
"It's very clear that NHL 2K11 is going to try to bridge the gap between gamers looking for more of an arcade experience and those looking for a simulation. I've written about the arcade-friendly Road to the Cup mode before, but yesterday was the first time I got my hands on it. It's essentially what you'd expect, in that you need to complete a bunch of mini-games to earn fans and then complete a hockey free for all (I wasn't actually shown that part, so your guess is as good as mine as to what it is). In other words, Road to the Cup is for those players who don't care about playing as real hockey stars and are instead content on letting their Miis pick up a stick and take to the ice.
For those looking for more of a simulation of real hockey, NHL 2K11 should meet your demands, too. When playing in traditional exhibition, the deep franchise mode or online team play (where five Wiis link up and every player on the ice is human-controlled), gamers will notice that skating is a bit simpler and more realistic this year. Gone is the turbo button and it's been replaced with more momentum-based skating that resembles the real thing more so than what was seen from NHL 2K10."
