I like to imagine a world where Secret of Evermore did well, financially. It doesn't help that it followed in the footsteps of Chrono Trigger earlier in the year, Final Fantasy 6 the year before that, and then one more year for its spiritual predecessor, Secret of Mana. The bar was so high! Part of its lack of success, though, was a pretty broken combat system (unbalanced), and a poorly implemented "search here" command, which rendered the player needing to swing their weapon spastically when trying to find hidden items. A cool feature with poor UX really hurt that game.
Still, SoE had some really great art, and a decent story. What a great first entry into his professional career for Jeremy Soule (composer), as a teenager just out of high school. Who needs college when there's opportunities available like that? ;)
Design decisions for software should take the interface into consideration. That said, I do think ring menu systems can work on PC and mobile. Some mobile apps have a context menu triggered by a long press, I could see a ring-type menu working there. As for PC, I'm not aware of that many examples, but the pop up palette in Krita is one example that could be easily adapted to be closer to a SoM/SoE-style ring menu.
It doesn't affect your point, but Secret of Evermore was actually very unusual in that was developed by an American team.
With the other point I raised, couldn't find something from the Minesweeper dev but did find something from the Solitaire dev. When asked about whether these games were included by Microsoft to help learn how to use Windows he said...
"A post hoc fallacy, I think."

This clip from Secret of Evermore (same developers, different series) shows the ring menu system:

Also, slightly off-topic but I'm not sure the article it mentions about Minesweeper being designed to teach people how to use GUIs is accurate, though it could have been an unintended consequence. IIRC Minesweeper was written by a Microsoft intern, I'll try to find the Reddit thread where the author discussed the story behind its development.
