NHL 13 is great... it's the longest I've ever played a sports game (even though I gave up on Madden and NCAA years ago, and just started back with NHL last year). I'm in year 5.
Pretty 'meh' on the NHL 14 previews.... just like Madden and NCAA, they've always focused on offense one year and then defense the next, so this year it's the typical "bigger hits! better fights!" hype that hopefully doesn't send it back down the road towards becoming an arcade game again.
