The game itself is great and comes with a small but great selection of default planes. There are plenty of high quality addons which can be installed for free. My personal favorite is the Zibomod 737-800. It can be installed for free and is super realistic from being able to manipulate about 99% of the switches and levers in the cockpit, to even physics and sounds. The simulator features a lot of cool things like
-Realistic flight models
-Detailed aircraft
-Amazing sounds
-Good scenery (with medium-high settings)
-A flight school feature for new players
The graphics and scenery may not be as good as MSFS 2020, but is very versatile and you can either download free aircraft (of varying quality) or you can visit the X-Plane store for payware aircrafts which tend to be more realistic and higher quality. Or if you want you could even just stick to the default aircraft.
But for the love of all flight simmers
IT. IS. NOT. A. GAME.
It is a simulator :)
