Hi,
I'm with MSFS since FS2000. For me few things are very important and I would like to have them in MSFS2020:
1. Reallistic ATC with SID/STARS, Holdings etc..........
2. Working and updatable FMC for passenger airplanes with realism similar to PMDG for all other airplane systems.
3. Reallistic and configurable AI Traffic with external editable Flightplans. I know it was before - but I would like to see AI separation, landing queues, holdings for AI, random emergencies for AI etc, no more disappearing planes etc.
4. Career mode for pilot with cargo or passengers experience (like in FS Passengers). Beside ATC and AI it is for me the most important thing.
The rest I would like to have was already shown on the videos
