Dead Machine wroteTwilight Princess is my least favorite 3D zelda; it's so ludicrously easy that it makes Wind Waker look like a Majora's Mask 3-day run, the world is the least welcoming and interesting to explore of any zelda world, the story is more ridiculous than usual, and the items are for the most part designed terribly and/or useful in only one place.basically, get Prime.
Don't listen to him. Though it is an easy game (nowhere near as easy as Wind Waker, though), TP has a great quest with the best dungeon design in any Zelda game, a well done combat system, and some damn fun items. Whether you get Prime first or whatever (Prime 3 is a great game), you should still check out TP at some point.
And for all Wii owners looking for a good FP shooter: Next week The Conduit comes out! Boo ya!
