Based from this video, You are given a freedom on which character control. So if you don't like Cloud, you can make another character the leader. Cloud will still be the main character and focal character but you have freedom to make someone else the "main character" when it comes to gameplay. As you see The player is maining Tifa while Squall and Aerith are AI. Its nice to see the love triangle working well as a team. You can switch character at will with a push of a button.
