Sailing, not something that inspires excitement. Being in the ocean for long periods of time with little interaction with things is definitely not something that would come across as a good game idea. This game changed that mindset. Zelda has always been about the adventure. Getting further from home or discovering new things with the new items that you find. This game does not disappoint.
Let me get the bad stuff out of the way, it's short. I promise. The biggest issue I have with this game is just one specific part and to not spoil it, I will just say that it is a huge fetch quest. It is tedious and incredibly drawn out. It is the only smudge on this otherwise great game.
Why is this game so fun? Simply put, it is a big adventure. A giant sandbox with no sand. Sure you have to sail everywhere but that is half the fun. Sometimes you run across an event or a monster or you see something in the distance that looks interesting. It's about setting out and seeing what you can. Sure there are parts where it is frustrating and you don't know where to go but that is half the fun. Figuring out where to go at each point and then what to do is fun.
Was this game as good as the other Zelda games? Of course, it's one of my favorites. Will it be remembered fondly by others? Not really, because of that one part that is just a minor flaw in the design, a lapse in judgment. Should you play this gorgeous game? Of course, what is more fun that heading out on an adventure just for the sake of adventure? Nothing.
