Big-Lipped Alligator Moment: No one bats an eye when Phoenix pilots World War II-era fighters, or has his wingmen do so — although some of the usual "This Cannot Be!" remarks from enemy pilots become downright hilarious when one considers that they're saying this as an obsolete subsonic propeller-driven fighter zips up behind them and tears them apart.
Hilarious in Hindsight: In Ace Combat 2, Scarface One's official aircraft was the Su-35 Super Flanker. The introduction to that game depicts his aircraft coming to the aid of a wingman flying an F-22. Fast-forward to Assault Horizon Legacy — now Scarface One's official plane is the F-22, and since the game uses Assault Horizon's cover art (which features an Su-37 Terminator), Phoenix is practically shooting down his old self!
While the actor's delivery isn't the problem, Final Fantasy fans may get a chuckle upon hearing, "Phoenix down!"
The first ace squadron you fight, Lancer, has a thing about knights and chivalry and honor and the like, much like some of the bosses in Zero did - and then you realize their lead's personal callsign is "Pride". It's like they held a contest to let a fan design one of the boss fights, and George Lucas won by doing his version of the Rot team.
