I've been a Zelda fan since the Ocarina of Time on the N64, which has always been my favourite game. Although no game since then has come close to the experience of playing that game, this one probably comes closest yet.
First off, the motionplus is an improvement on the old Wii controller, but actually it isn't as perfectly accurate as everyone is saying. It's better, but not absolutely spot on. There have been a few occasions where I've been frantically waving the remote around trying to get the sword or insect net moving, but it doesn't work with the precision I was expecting. Plus you have to recentre it constantly, because it gets lodged in the wrong direction, which is a little frustrating.
Gameplay is excellent. Bit of a slow start, but after the initial instructional sections, you're flying your loftwing, catching bugs, killing enemies and solving puzzles, having loads of fun doing it. It's the same Zelda formula, but it looks amazing and has been given a comprehensive upgrade in almost all areas.
Really, really good fun. Could (and have) play it for hours.
