The company has rethought nearly every aspect of the FF franchise, from the battle system to the use of voice acting instead of text and beyond. Nearly every change will be jarring but nearly every change is for the better.
It's basically the vehicular combat equivalent of a fighting game like "Tekken" or "Virtua Fighter"—each character has his reason for entering the tournament and you can play your way through a set of scenarios to complete their quest.
The game seems to hearken back to the successes of "Ace Combat 2" by adding fair doses of realism with a good amount of action and intensity. The game's biggest fault lies in its brevity, as it ends much too soon.
