I am a big fan of the Zelda series, and having not owned a gamecube or N64 in the past and so being unable to play many of the bigger zelda titles (such as ocarina of time and the windwaker), i relished the chance to play a 3D one when i bought the Wii.
It didn't disappoint. This is one of the best games i have ever played. I found myself playing it for hours on end.
The controls are one of the best things about this game. From thrusting forward with your shield, to hacking at your opponent, most of the controls make use of the Wii's unique motion detector abilities. Sadly, there are some attacks that consist of pressing buttons, but all in all it doesn't make it much worse.
The one thing i could find fault in this game was the lack of difficulty. After i had finished the game i looked back on the difficulty, and once i thought about it, the only times i ever died were from accidentally jumping off a cliff, or into a pool of lava etc. - none of the enemies were ever difficult. Sure, there are some moments when you get frustrated because you can't land a hit on that one swordsman with the massive shield, but after you keep at it for a while, it's easy. That said though, i never thought about it while i was playing it and i thoroughly enjoyed the whole game and was disappointed when i finished it.
I'd say the game would take about 25 - 30 hours to complete the main story, but then of course there is all the side quests and minigames. From fishing to finding poe's to steal their souls, to trying to find that last golden bug... this game is full of sidequests that will have you tearing your hair out if you choose to pursue them.
All in all, this is one of the best games i have ever bought, and would recommend it to any fans of adventure/RPG games.
A fine addition to your Wii collection!
