It looked like a remake of Ace Combat 5: Unsung War to me. A Female pilot named Edge is mentioned and looks to be a selectable wingman, but then there is the name Phoenix that isn't in AC5, but that might be a rename for Blaze or edge is a bonus wingman. However, a more likely explanation is this contains levels and the story from all the games in that time line.
Despite looking better every year, levels now are little different from the first AC. I hope they make the AI a bit more aggressive. As much as they want me to feel like some badass pilot, you think in a 6+ to 1 dogfight there would be more missiles in the air.
Making ground attack jets more usable would be great like giving the A-10 a bigger gun rather than the same bloody gun ever other fighter has with bigger/more diverse stores of ground weapons. Currently there is no reason to ever use a ground attack without being forced to.
