Also, noticed elsewhere, that there is a free Update 2.7 offered to ALL GSX users.
Which means all the updates you saw in that video, applies to the base GSX product. None of them requires the L2 expansion, just install the latest GSX, and you'll get the latest version of everything.
The L2 Expansion is only required for:
- Animated passengers in SODE jetways (made by GSX or by 3rd party sceneries) and on stairs
- All default jetways for default airports automatically replaced by GSX with SODE jetways and the ability to customize (or download pre-made customization ) for 3rd party sceneries
- The new Fuel Hydrant service.
And all of this, like has always been, only applies to non-FSDT airports. At FSDT airports, the whole GSX+L2 features will always be free.
