GSX will allow two customizations levels:
1) Repaints:
- These can be easily done by us, or by users as well, and we'll try to provide paintkits for all vehicles. Repaints can be regionalized in a very flexible way, allowing a certain vehicle to be present in a specific continent, country or airport/s. Repaints can also include things like humans clothing and faces, we'll include some variations based on ethnicity for example, to be seen in different countries, but users can add their own and share them.
2) New models
- These are extremely difficult to do, since they require both special modeling with an FSX SDK that we partially modified ourselves, and will also require programming, which means is outside of the reach of users. For this level of customization, we are thinking about GSX "Expansion Packs" to cover specific areas of interest. We might have a GSX Cargo Expansion Pack, for example, and a GSX Bush Expansion sounds like an interesting idea.
In any case, the initial release will focus on airliner operations, even if the product will technically support all FSX airports, the most suitable places will be airports with a least some parking stands and a taxiway layout so, the lone strip in the countryside might not really work with it, and the default vehicles sets is mostly suited for mid/large airports.
