Ace Combat 6 is a great game if your into flight. Its realistic at the beginning, but towards the very end, it gets in a "f**k logic" mood with a(spoiler alert) giant cannon that fires cruise missiles 3000 miles away and a fleet of giant hangers/ attack planes.
If your in for the Multiplayer, stay far away from this game. I spent minutes waiting for a match, and 2 people showed up.
There are also many other planes aside from the ones built in game available in the Marketplace. I recommend the CFA-44 Nosaforatu(Strong machine gun, special missile launcher, and extremely fast), if you buy the game.
The graphics are great, and it also provides a pilots seat point of view, a clear 1st person view, or a third person view that lets you see the entire plane. The FPS is high enough to see the shape of a passing plane at 600 miles per hour.
Since the campaign makes most the game, seeing no one plays Multiplayer, the story is incredibly retarded until the very end, and even then it doesn't matter much. The story at the end with Garuda 2, your wing mate, is much more interesting.
