I recommend Ace Combat: Assault Horizon. It was fun, fast, intense, and quite good looking as well. And if you're on a console, and want a new flight game, get this one.
And when I was done, I had to go find a copy of Ace Combat 6, because my only complaint was that unlike the previous Ace Combat games, there was no rediculous Japanese bent plot element, like flying aircraft carrier missle platforms, or anti-asteroid defense cannons. Which won't be a problem at all if you prefer more realism. It's just that I prefer the strangereal.
