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).

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.
I just realised I made a mistake; I thought this was a different, Linux-specific community. I apologise.
