MyCareer is where the bulk of NBA2K13's singleplayer Experience
is to be found. In it, you can craft your very own rookie, choose his attributes, and train him up until he becomes a world-renowned player. This doesn't just include training, however - in fact the mode now supports various off-court activities, and takes a lot of time and management to get used to all its nuances.
The ultimate aim of MyCareer is to score yourself a position in the coveted Hall of Fame. As you are just starting out, you will have to define a few parameters about your soon-to-be-superstar player.
