Before Skyrim, Oblivion, and Morrowind there was Daggerfall, the second entry in what has become a household name for fantasy RPGs. The original is available on Steam and GOG, though 23 years later we have a modern remake in the form of Daggerfall Unity which brings in modern graphics, controls, QoL improvements and mod support (as well as Linux and Mac support).
Just because the company has been scummy doesn't mean that unity stopped being one of the best free game engines available. I like godot but it's not even close, they just don't have the resources and man hours spent yet.
I never said it was GNU certified free as in freedom, libre software. Its free as in you can just fucking download it and use it without paying. You're being a pedantic asshole and people wonder why the FOSS community isn't more popular.
Why are you being intentionally obtuse? It is free. As in, you can use it for free without paying anything. It's not Free Software as defined by FSF, but it's free.
