To me, flight simulator can be considered as a sandbox. In it you can mess about and fly under the Eiffel tower etc, but also you can learn how pilots do things for real.
I created the FS ACADEMY line of tutorial missions, based on my own training from PPL to A320 Captain.
MSFS has the potential to host whatever kind of activity you want to do. For me it’ll come into its own when Fenix release their A320, which will be great for my studying. Others want to go and explore the earth in a new way, much like how many of us spent hours on Google Earth when that first came out.
