The airport of Lanyu Island in Taiwan, which is actually called Orchid, has been released as freeware for X-Plane 12. It comes from the developer FS Formosa and "weighs" a good 340 MB. However, this sounds quite plausible, as the preview screenshots promise an extremely detailed implementation. You can get the exotic trip to the Asian state of chips and semiconductors completely free of charge here in the download database of X-Plane.org.
