why do you think there are so many really loving bad games nowadays
The cost of making a game is high enough that publishers are weary about taking chances exploring new ideas, and a lot of developers are more out of touch with gamers these days.
Ocarina of time was among the first games to really adopt the whole 3D action adventure genre, clunky gameplay mechanics are a little more forgivable since at the time, there wasn't a whole lot of experience to go off of.
The point is that as time would progress, the developers would expand on ideas and improve aspects of the series that fell short in the last title. This is why Majora's Mask was a way more fleshed out game compared to Ocarina of Time.
