Hello there, All-Star!
If you own a copy of NBA 2K17 and now have NBA 2K18 in your video game library, you may be wondering if you can transfer any leftover VC from the former into the latter.
You can't transfer VC between versions of NBA 2K. That not only includes different console versions of the same game (i.e. PlayStation 3 to PlayStation 4, Xbox 360 to Xbox One, PS4 to XB1, etc.), but different entries in the NBA 2K series (like NBA 2K17 to NBA 2K18).
