OOT's scope really was well beyond any other game at the time it had some flaws in it but the sheer ambition of what they pulled off made up for it as the wasn't any game like it
Pretty much; back in 1998, the sense of adventure, scale, and sheer epicness was unparalleled, it really did feel like the video game equivalent of something like The Lord of the Rings. It wasn't until BOTW that the series recaptured this feeling that it was pushing the boundaries of video games as a medium.
Honestly, as someone who played both TES: Daggerfall and Might & Magic VI before OOT back in days, I found it to be a charming game, but actually nowhere near the scope of those two games. Not the same genre, but if we're talking pure adventure, scale and exploration it was severely lacking compared to them.
Admittedly, console and PC gaming were quite apart in those days, so I doubt many console gamers had a chance to experience these PC games, so I can see where this line of thinking might be coming from.
