NHL 2K6 was far from a good game last year. It was exactly the same as 2K6 for the PS2 and Xbox, just with a $60 price tag. NHL 2K7 is a whole lot different and a whole lot better. My review ( Basically just for you Marc ).
Graphics: 4.5/5 The graphics are really good. The cut scenes look good, the rinks look great, but some of the well-known skaters don't look quite like themselves. Also, the fans look pretty strange too usually. The one strange thing about the graphics though is that there is a weird looking fog or something that is on the rink. Pretty strange.
Sound: 4/5 Nothing worth noting. The crowd seems quiet most of the time, the soundtrack overall in this game is poor, blah blah. You do get to decide, though, whether you want to play to music or play with commentary. Both are good choices; depending on what kind of music you like.
Control: 4/5 It works just fine. Anybody can pick this game up and use the controls. The one problem with the controls is how when you use the right analog stick to deke, the player will deke for what seems like forever, so it's quite easy for another player to steal it. That is one fault to the controls in this game. The default camera angle is great, by the way; giving you a great view of the rink from all sides.
Fun: 4/5 It's a hockey game with improved graphics, basically. There are some extras, but we've seen them before: air hockey, pond hockey, unlockable jerseys, and so on. The online play is pretty good; much better than NHL '07. If you are a hockey fan, then you should rent this game. Hockey season just started.
