Ok, so I've got both Sky Gamblers games. IIRC, owning one will unlock a special aircraft in the other and vice-versa. Neither is installed at the moment, and the WWII version has never been installed on my device. I do have a cloud save from the modern version. I don't sync with my PC, though iTunes (on my PC, not my device) is set to auto DL any purchases made. I don't want to screw this up, so, can someone inform me as to how the games verify that the unlock conditions have been met? Ya know, should I install one of them, launch, exit, install the other...etc?
