Hi Guys,
I made the mistake of buying this game too, for PS2 but there is a way to get NBA2K7 if you want. You can take your game back to where you bought it and say you think there is a glitch and they will give you a new sealed copy, they will not give you a refund or exchange for a different game because it has been opened. This is what EB did for me.
Then I took the new NBA LIVE 07 to my local Best Buy and told them i got it as a gift but i already had it and wanted to exchange it and they let me exchange it and I did so for NBA2k7 which has MUCH MUCH better--- Gamplay & the Graphics are way better. Its like night and day trust me on this.
Just wish the menu layouts were as good as Live's though.
:P
