Ace Combat 6: Fires of Liberation (FOL) definately brings the series back...
The graphics are simply nothing short of breathtaking. The planes are all modeled so realistically, that if you didn't know it was a game, you would think that it was real. When all you have to model is planes a buildings though, it's not hard to make things look so pretty.
The Sound is very well done, from the sound of your engine screaming through a high speed turn, to the sound of your machine gun firingthrough the air, the game is perfectly spot on. The voice acting for the cutscenes, is also really well done, and every character's voice matches their individual look and model.
The game is hard. Plain and simple. If you are new to the series, you will definately want to play on easy. I like the normal difficulty myself but for newcomers, it's best to start out slow. Thanx for reading, and I hope you enjoy the game as much as I do.
