There have been games that showed hints of stuff you could get to, but I think BOTW was the first major open world game that actually universally followed that rule and didn’t have invisible walls all over the place.
Like Skyrim there was a lot you could “climb” by abusing the mechanics and spamming jumps until you got lucky, and everything existed in that sense. But it was glitches, not part of the mechanics. BOTW having points of interest almost entirely discovered visually was unique.
I’m not downvoting, but the fact that kernel malware games don’t work is a feature to me. It would be a full time job to keep from installing anything that demands obscene access for no legitimate reason on Windows. “It doesn’t work” is way easier.
Pretty much everything else on Steam works without effort.
