I don't think it would be worth HTC's time and effort to create an .exe specific to any particular platform other than Windows. That said, if the normal game can be run on a mobile device, whether directly or through emulation, then any limitation of gameplay would be entirely up to the end user. Since nobody would carry around a USB flight rig on their way to Starbucks/Grandma's House/Atlanta, taking out a tank or a PT boat is a reasonable compromise. But that has nothing to do with HTC.
