With all of the games graphical prowess it appears that it's not as good as previous Ace Combats.
Taken from review:
"I've been playing the Ace Combat games for about five years. I own 4,5, 0, X and now 6. All of them are really solid games, but it's gotten to the point where they can't evolve the franchise anymore. Does this make the game bad, well for starters no. The game is solid, but it's not the best in the franchise. That prize seems to be held (in my opinion) by Ace Combat 5: The Unsung War. In many aspects it seems to be half the game that Ace Combat 5 was. You have half the planes, half the missions and a terrible story."
