Activating the game is just the beginning. As you progress, you will "unlock" more of the game's world:

: Some resellers sell "Gran Turismo 7 Keys" that are actually login credentials for a new account. Sony considers this a violation of their terms of service, and these accounts are often banned or reclaimed by the original seller later.

: Unlocked after completing Menu Book No. 4, allowing you to buy cars from 2001 and later.

Happy racing!
