I'm enjoying it so far (on the Wii U; it's my personal system and I don't want to be a third person fighting over usage of the Switch). Some of my excitement has been damaged by spoilers; watching two others play a game that I'm also playing means that I already know where to find a lot of things, or how to solve certain puzzles, and it's a lot less exciting than solving them myself.
I do wish I was playing on the Switch, though... I can't be as free as them, grabbing the Switch and going. It's too easy to accidentally think, "Hey, I can do that!" with the Wii U and then walk out of range of the base system. Then I try to work out schemes of how to take it around with me... And then the Wii U Gamepad's screen is so blurry in comparison to the nicer one on the Switch.
I do have a few issues with this game. One - Zelda games have taught me to pick up everything. If it's not nailed down, pick it up. This game changes that around to a more Skyrim/Fallout system, where inventory space is a premium. I've always had an issue with those games, thanks to being trained to be a kleptomaniac... by Zelda and other games.
Two - the open world. I have a few issues with it. I love the idea, but at the same time, part of my enjoyment of Zelda games was being funneled into puzzles and then solving the puzzles. I could derive even more enjoyment when I found unintended ways to complete the same puzzle or to break a sequence. Also, I always knew where to go in older Zelda games. I always had direction. I could go do whatever I wanted - to a point. Eventually I'd complete all the sidequests that were possible at that time and have to go back to the story. Here, I'm overwhelmed by a vast world. Having so many options for where to go is actually tiring. There is far too much out there to really explore everything. As a result, as your options for exploration are unlimited, it's a lot easier to miss overworld secrets.
Three - Combat. Since puzzles are a bit more free than before, I feel like they stepped up combat in exchange. Experiencing OHKOs are kind of annoying. Seeing the Game Over screen a lot is discouraging. Making a single, minor mistake can cost you your life. (Gotta say, though, props to the save system - it's very good about minimizing losses so that you can learn from your deaths in a similar way to learning from your painful mistakes in past games.)
So... my complaints are not necessarily bad things. They're just different than what I've come to expect from Zelda, and so are things that frustrate me personally. I do love that they've changed things up, though. As Ray mentioned, so little tutorial. (Which actually annoyed me the other way, because I didn't have a full grasp on the controls at the time they let me go, so I had to keep working to figure things out again. The game manual is useless.) I'm getting the hang of it, and enjoying the game. I'll keep playing, but I don't feel glued to it like I have with some games in the past. I think this is more a function of me changing as an individual than a statement on the game's quality. Actually, that's pretty much how I play games these days - bite-sized chunks. I don't finish them quickly, but the ones that I'm truly enjoying, I tend to keep coming back to and progressing on. (Picross games, Zelda, Pokemon Moon, Final Fantasy XIV, etc.) That's what I'll do here.
