If you've downloaded and played through The Prelude on PlayStation 4 and Xbox One, you may want to try to play through it again. We don't blame you: It's a lot of fun.
However, The Prelude is designed to only be played through once per account/gamertag on a console. In the full retail version of NBA 2K18, you'll of course be able to play through/restart your MyCAREER game as many times as you'd like.
Please do not delete your saved data. You won't be able to restart The Prelude if you do this.
