I've played both NHL 2K7 and, NHL 07. As much as I enjoyed playing NHL 2K7, I enjoyed NHL 07 more. Let me explain.......
First of all, I am not a big hockey fan. I do know about the sport but, had little knowledge on how to play it. So, I decided to experience a new challenge. I decided to buy NHL 2K7. Why not NHL 07? Because at that time, NHL 2K7 was cheaper. So, I went with the cheaper one.
Immediately, I was impressed on the presentation. It seems to be the biggest emphasis of the game. The graphics and game play, are very good. As I played the whole season, one thing I did notice, was how much I dominated the game; not on rookie level, with ease. Anyway, my brother knowing that I finished and got rid of the game, stressed for me to try NHL 07. I did not have in mind of buying it until the fall. But, the game became cheaper; Best Buy-$19.99, so I decided to buy it now.
Immediately, I noticed that the presentation was not as good as NHL 2K7. However, the graphics was just as good. And, here's the difference, the famous stick.
I have read many reviews on both games. Many, unfairly to both games and in my opinion, because the individual reviewer either liked 2K games or, EA. Me? I like 2K games more. But, in this case, EA much more.
Back to the stick....it makes you feel like you're playing an actual game. Also, there are no speed burst in the game; not that I know of, so the speed of the player is what it is; unlike the 2K7 which has it-I believe the one of the back buttons.
I have found that playing the 07 game, it offers a more true game feel of the sport. So, I guess it is up to you. If you are making a decision based upon brand, then the choice is obvious. If you want a game with a little more challenge and more of a feel of the sport, then the EA is the choice. Either way, both games are good.
