Honestly i feel that MSFS should offer way more than it is right now especially with the amount charged for purchase. And this should be applicable to both the PC and X Box versions.
There should be all inclusive in-game mocrosoft liveries for airports, aircrafts etc. I agree that there is the market place for mods or addons but these often results in performance issues or bugs as some developers are not coding properly.
Also MSFS should also invest in larger aircrafts all versions of boeings and airbuses etc (have more commercial planes than small planes) which people are interested in.
There only thing i would give a 5 star rating on is the graphics other than that i feel MSFS could be more realistic in all aspects of the game from adding passengers, crews, apoirt staff, etc
