Good, but not great. XBOX version is okay compared to the other platforms
Specific to the XBOX is the control stick feature. Basically the right thumb acts as your stick while the left thumb is your skates. If your an experienced EA Sports NHL'er it takes a bit to get used too, though practicing in shootout mode is a lot of fun, but for new comers this is quite easy to grasp. You do have a bit more control of the puck and can do some great dekes and spins. There is no deke key so players will need to master this in order to perform spins and out play their opponents. AI is good and in the Superstar difficulty the CPU gives you a tough game.
If your looking for a good hockey game this season and your only gaming platform is an XBOX, then you may want to rent both NHL 07 and 2K7 and decide on which one suites your fancy. My 2cents.
