I am new to the Flying Community and intend to purchase MSFS 2020 shortly . I was told that there are some restriction that MS puts on you in the verson purchased directly from Microsoft and that I should buy my copy from Steam online. Is there any truth to that ? Will I be able to learn the Simulator and do some Flying with only a Mouse ? or is a Joystick necessary ? I appreciate all your comments and suggestions . As I said , I'm new to this world of Flying.
