If you are one of the people who have tried opening X-Plane 10 and been put off by the complexity of setting it up, you will be pleased to know that the NEW user interface is being reworked with a quick flight screen. This will allow you to pick your aircraft, location and weather in a simple user friendly manner before loading the scenery and speeds up creating a flight enormously. The next update to X-Plane (10.10) will fix this user complaint and add many other features.
The X-Plane developers are listening to users and third party developers to make X-Plane the best simulator on the market.
A further update in progress will release World Editor 2 giving the flight sim community a simple to use drag and drop tool for creating airports. A user can look at a plan of their local airport and build a replica with the correct building types in the correct location on a top down view live in the sim using drag and drop technology.
Hangars automatically position with doors facing airside. A multi-storey car park is simply dragged out of the ground to make it as many storeys high as the real car park. Does your terminal have a different style of windows, simply swap them over using the interface. Although not the same as a custom third party airport package with photo textures of the exact buildings, the library objects give a close approximation of the real thing.
As the buildings are library objects, a simple text file is generated to control the placement and the created airports will then be shared. Every time you update, your world airports will be populated with replicas. These will be closer to the real thing than having random generation of airport autogen and the building are truly three dimensional. Features like windows and doors are really 3D, not just textures on boxes.
While waiting for these updates, check what you are missing and see the quality of X-Plane 10 in action when even using the currently available add-on packages and even airports imported from FSX packages. This video shows just how good X-Plane 10 can be. The Youtube page lists the scenery and add-ons used.
