NuOxygen has just released "The Racing 3D Flight Simulator," Ikaro Racing HD for iOS devices, and it's looking pretty neat. Players will race through a diverse set of environments (and 22 tracks), from sprawling cities to winding canyons, jockeying for first place. It won't be easy, but it makes winning that much more satisfying.
The game is designed to steadily increase in difficulty, so that players adjust naturally to the curve. It's meant to be more pleasant than panic-inducing, with cameras that highlight the beauty of the landscape or the details of the planes so that the visuals can truly be appreciated. Of course, spending too much time drinking in the details are a good way to end up face-planting into an obstacle. A danger that becomes even more real when the dynamic weather system opts to replace those clears skies with a thunderstorm.
Ikaro Racing HD was designed with the iPad 2 in mind, but it's also available for most other iOS devices. It just requires some tweaking in the options menu first. Aspiring air jockeys can grab it off of the App Store right now for free.
