People don’t explain why you’d want expert controls. If you don’t turn them on, the game won’t let you rotate your plane. In other words, no flying upside down which takes away a lot of the fun tricks you can do. The game will correct anything you try to do to make sure you don’t rotate the plane which means you basically just fly around in straight lines chasing enemies the whole game. Also, holding Triangle will make the camera face the enemy your locked onto, this makes it easier to track your target if they fly behind you.
Just wanted to say this game clears every other entry in the series by far. It took the best parts of each Ace Combat and welded them together beautifully. Genuine GOTY condender, can't wait to see you play the whole thing.
