Hi,
I notice there are no installers for FlightGear. FlightGear is one of the major opensource projects. There are snap and flatpack installers available that could be added for example.
Flatpacks allow easy install on steamdeck for example.
More info, see packages list:
libregamewiki. org/FlightGear
There are also very old screenshots on the FlightGear page that should be removed. The ones with short names like fg1, fg2, flfl, cockpit1, and a duplicate of a newer screenshot … But there doesn’t appear to be a mechanism for doing this.
Cheers
