Exactly, it is really ironic that while the game aims to simplify things for casual players by making it more of a “game,” they are expected to use tools like Simbrief for flight planning, which can be more time-consuming. Casual players probably won’t want to spend that much time on complex planning.
Your experience with the Asobo A320 in 2020, where you could quickly set up a flight, highlights the importance of having an integrated flight planning tool. The new EFB in MSFS 2024 should definitely offer this level of convenience for all aircraft.
I hope the developers recognize this need.
