Yep, this game is amazing.
Found myself losing time last night just going off the beaten path. There's always a distraction and something new to find and do. I've only done 2 shrines too.
I really like the music, it adds to the atmosphere and immersiveness amazingly. I know its a common complaint as it's quite minimalist, but it aids in the world feeling alive. You can hear the birds chriping and the squirrels running. A catchy tune would almost certainly take away from that.
I think my main draw is the fact everyone's adventure will be different thanks to the enormous variety of things to do, and sights to see. I found this bubbling bog oddly beautiful as the sunset was hitting it, highlighting the shades of grass around it.
It just begs the question where the series goes next. No doubt they've got a winning formula here, but it'll be interesting to see if there willing to take even more risks thanks to the positivty of dropping series staples here. My dream of a Zelda MMO might actually come true haha.
