A lot of good titles have already been mentioned but holy crap no one said MotorStorm: Arctic Edge? Such a great racer, very polished and it has unique mechanics and a ton of fun vehicles to make it worth your while.

Also: Ace Combat X: Skies of Deception. If you’re looking for an arcade flight sim, this one is for you. (I’d steer clear of it’s successor Joint Assault though.)
