Here's how to create an account:
- Select System Settings on the HOME menu.
- Scroll down to highlight Users, then select Add User.
- Click Next.
- Select the icon you would like to have associated with your new account.
- Once you have selected a character, enter a nickname when prompted.
- Select OK again to confirm.
At this point, you will be given the option to link a Nintendo Account to your user account. This step is required in order to play Rocket League online. Unless you follow the guide right away, here's how to do that later:
- Select System Settings on the HOME Menu.
- Scroll down to highlight Users, then select the appropriate user account to access the Profile Settings.
- Select Link Nintendo Account.
