I'm gonna be cool and now post exactly according to the thread prompt.
Favorite Zelda game: Depends on what aspect of the game merits the most recognition. For sheer exploration and visual charm, Wind Waker takes the cake; for depth and maturity, it's got to be Majora's Mask; for longevity and realism, Twilight Princess is peerless. Overall, though, I'd say TP reigns supreme--sure, it's not that original, and maybe it's just the world's fastest nostalgia talking, but I really do feel like I got the most bang for my buck out of that one.
Favorite weapon/item: Well, probably the Hookshot, for its versatility and uniqueness. I keep feeling like there's some other, better item I'm forgetting, though...
Favorite dungeons: I love Snowpeak Ruins and Goron Mines. The Stone Tower is... well, it's creative, at least.
Least favorite dungeons: Pretty much anything from Phantom Hourglass. Also, infamous and generally frustrating though they may be, I think the only "Water Temple" I've really hated is the one in Majora's Mask.
