This could have been the handheld Zelda we've all been waiting for, if the developers hadn't been intent on repeating several of the mistakes that made Phantom Hourglass such a disaster.
That's not to say there isn't a lot here that's done right. Innovative uses of the microphone, and fresh takes on old items give this game a feeling of novelty - when they actually work. Sometimes the microphone functionality is spotty, and when you need it to be on point to defeat a hulking boss monster, that can be a major drawback.
The primary source of my ire in this game is the very thing that defines the gameplay - the train system. It's as if the developers of this, Phantom Hourglass, and Wind Waker said to themselves "People complain that they aren't spending enough time staring at the screen, waiting to get to their destinations." This addition is about as dynamic and engaging - and about as much fun - as a load screen, even with the tacked on "can't be defeated, so you can see in advance that you just wasted 5 minutes on a trip that can't be completed" phantom trains.
All in all, what made this game so frustrating is what made A Link Between Worlds such a knockout - it's lack of emphasis on dungeons. That is, after all, why people pick up a Zelda game.
Though I rented it for only so long I recently bought the game. I loved it but still haven't finished it. The game has a variety of Enemies like most Zelda games and an awesome storyline. It's to bad I lost it.
