Either Zelda has some wild replay value or you're a little obsessed at this point.

Well, it has decent replay value. Given just how non-linear and open it is, along with literally everything being optional, I've played through multiple times without doing it the same way twice. Each puzzle has nearly infinite solutions if you approach it different ways, so it's fun to try to solve them in unique approaches. So with every run taking 50-100 hours, depending on what you do, that adds up quick. Then add to that how I really enjoy the speedrunning of the game, and you take just a few playthroughs and multiply that exponentially just to practice the runs. And with such an open world, there are lots of great speedrunning categories to enjoy.
