It should not be a surprise to say I like and am intrigued by air combat games - whether in simulated form, or more action-focused fare.
But what happens when you try to take those concepts from 3D-based air combat games, and translate them to a (primarily) 2D system like the Game Boy Advance?
You get Deadly Skies (aka Airforce Delta Storm aka Airforce Delta II), a thrilling display of aerial action which manages to show off some altitude, despite playing from an overhead view.
