So “easy to install” is not really issue here, since it eventually can be distributed in marketplace regardless if it’s gonna be free or not. Problem is that it needs to be free in order to integrate different language. Would be good start if we hear from Epic reasoning behind that point in EULA, i think it might have something to do with compatibility with more restrictive platform licences like PS4 or Xbox One or even iOS
I got idea for potential workaround: Make runtime and compilation things free and tools that they showed in there video paid as a extra. But i’m not sure if Xamarin is ok with something like that.
