A basic overview of what will be lost is as follows:
- Play Now Online, H2H games with friends, etc
- MyTEAM
- MyCAREER (the offline version of the mode hasn't existed since NBA 2K19)
- All unused Virtual Currency and MT (there's no option to transfer an unused balance to NBA 2K22 or NBA 2K23, as nice as that would be)
- In-Game Roster Sharing
- Official Rosters (if you uninstall and reinstall post-server shutdown)
With that in mind, it would be a good idea to wrap up any business with NBA 2K21 ASAP. Finish what you can, spend the in-game currency if you want, and download any rosters. We have ways of sharing rosters offline for the PC version of NBA 2K21, but console gamers are unfortunately out of luck there. Of course, it's still worth grabbing any rosters on PC before the shutdown, as the in-game sharing functionality is certainly more convenient.
Feel free to share any suggestions for rosters that others should download before the server shutdown!
