So, it's probably just me having not touched NHL 12 in a while, but the NHL 13 demo just feels....clunky. Board play is terrible, hitting seems to be a tad bit less inconsistent, the new left trigger dekes are going to be fun to put to use and they've actually improved goalies a bit. Oh, and poke checking seems to be a bit more consistent as well, though it now seems way too easy to lose puck control.
Hopefully I'll be able to snag a copy shortly after release, money's a bit tight though so I'm not sure.
