Don't get me wrong, I've replayed BOTW 4 or 5 times and enjoyed it each time, but there wasn't the sky and all of the depths and caves to work through as well. I just find it a bit tedious now constantly throwing/firing brightblooms or breaking wall after wall after wall after wall after wall...
I personally feel it's a great game, and whilst still on my first play through, I already know I probably won't play it again for a few years. It will all seem like a massive chore. It's probably just me, but it feels like there's now too much to do, in return for not a lot.
