What does HackerNews think of UnrealEngine?

It is not publicly available. If you click on this link you get a 404 page: https://github.com/EpicGames/UnrealEngine You actually have to go and subscribe, agree to their terms, and then you get to view the source code. It happens to be free, but it is by no means "public". (I also don't have a problem with their license. Their business model is more than fair.)

Thanks for the response. It's not public, but it's accessible [0].

    git clone https://github.com/EpicGames/UnrealEngine
    cd UnrealEngine

    pijul init && pijul add . -r && pijul record

should bring your machien to a halt!
