Without wasting any time, we're going to address the big question: how does MetalStorm: Wingman compare to Sky Gamblers: Air Supremacy. They both have a colon in their name. Satisfied? No? Fine. Sky Gamblers is a graphical masterpiece. That's why Apple picked it to show off the capabilities of the new iPad during its unveiling.
That said, both games are extremely polished, and both offer an incredible multiplayer dogfighting experience. You can't go wrong with either. But...last time we checked, we were FREE Apps Arcade, not $5 Apps Arcade. The winner, by unanimous decision: MetalStorm!
