I define the priorities by looking at what is needed to enhance the experience of an IFR flight, nice to haves are indented:
- Airplanes (DASH 8 is great, B737, B747, Learjet 45, A320 are ok. I reccommend before adding new planes to enhance the latter airplanes, engine start, FMS, lighting etc. I think to have only sophisticated, fully real airplanes can discourage new users. It would be good to have the existing airplanes in a simple mode, e.g. press S to start the engines, automatic flight plan creation from A to B. People can then change later to full mode)
- Flight Plan (SIDs, STARs, fligt plans can be saved, maybe only for some chosen airports to start)
- ATC (IFR clearance, Ground, Departure, Approach, Vectors to ILS etc, maybe to start with only between some chosen airports)
--------------- Ground Services (at least push-back)
--------------- AI Traffic (maybe leave to 3rd party developers to gain resources for other inhouse projects)
- Night lighting (not just airports, but cities, streets, towns, cars)
- Weather
---------------- Cockpitbuilder, make use of Saitek/GoFlight and other modules
