The fact that you can hack some aircraft if the files are open is a positive aspect of MSFS, but they are two entirely different development processes, and in no way comparable. They no doubt even differ a lot between different dev companies.
You can always start your own dev shop if you think it’s that easy😜
As I said, I like Dak, using a couple of different mods. Don’t have any real issues with it. I can even shut one engine down to see how it flies on one👌Well worth the price!
The Denarq Twin Beech - Beech 18 improvements mod. New Update 1.5 is out is another good example in addtion to the DC3 Duckworks mod (and others like @NixonRedgrave ), and that was a lot of work to do. Kudo’s to the hardy souls that take those hacking challenges on!
