If you just so happen  to purchase the recently released NBA 2K9, you are in for a surprise. When you go to install the game you will realize there is no CD-Key to be found. Why though? Well, it seems 2K Sports forgot to include one, rendering the game seemingly unplayable.

However, quickly jumping to their aid, in a statement to Shacknews, Valve announced that Steam will fix this problem allowing users to install, and play, the game regardless of a CD-Key or not, provided the retail CD is in fact in your CD drive:

Owners of the retail version of NBA 2K9 for the PC may now install their games without the CD key, provided the disc is in the drive. And those considering a purchase of NBA 2K9 may do so without concern of installation issues related to the lack of a CD key

While the game is also available for the PS3 and Xbox 360, the console version of the game remains unaffected.
