If you are using the steam version try verifying your game files, if that doesn't work try using a different aircraft or departing/landing at default airports and see if you can narrow down the cause of the crash.

My only concern is add-ons, but Microsoft will probably make a system where you can get them on XBOX too, and also joystick compatibility.

My PC is not able to run FS2020 as far as I know, I am just wondering cause I want to know what parts I should get if I were to build a PC, and what performance I would get with them.

How well would FS2020 run and look when running the minimum specs?

FSX and P3D have their pros and cons, I use FSX due to it being cheaper but I admit P3D is a better flight sim but both have advantages and disadvantages, some of the main advantages for P3D is stability and it being 64 bit, but for FSX you can use FS9 aircraft if they are ported which as far as I know you can't for P3D, also FSX has been out for longer so there's a larger quantity of addons, freeware and payware. If you're on a budget FSX is the clear winner because the sim is cheaper, and the addons are cheaper, but if you are willing to spend more money then get P3D.
