It is looking like everything in 2K13 is going to be based around that VC currency. From MyPlayer accessories, signature skills, and mini-dunk packages, to MyTEAM, and even unlocking players for Blacktop mode, it all costs VC.
Early videos show the game constantly communicating with the 2K servers, meaning that VC amounts aren't stored locally when online....but we play on PC (most of us), and people will mostly likely find a way around such restrictions.
I am going to do my damnest to NOT cheat, not inflate my earned VC, and not gain access to locked items for my MyPlayer. Reply if you are going to do the same, and if you do and then end up cheating, reply again for shunning.
