Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.

Grand Theft Auto: Chinatown Wars
Touch minigames and top-down driving need modest dexterity
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.

Grand Theft Auto: Chinatown Wars

Grand Theft Auto: Chinatown Wars
