If you're looking to collect all Zelda games, then I would suggest purchasing Twilight Princess. I had only played the DS titles before tackling this one, so there may be awkward transitioning if you aren't used to Z-Targeting (unless you've played the Wind Waker). I thought the game was pretty good. It does borrow tons of ideas from Ocarina of Time, but I didn't really mind it as much as others since I was playing Ocarina of Time alongside it on the DS. Whether it's worth the buy as just a game to play, I'd say it is, but that really depends on taste. TP is a teen-rated games with more mature themes. it's still Zelda, but it really won't be what your used to as far as the style is concerned. And if you're more on the picky side when it comes to characters and storyline, then you may not appreciate it as much as I did (I'm not really picky with that sort of thing. I play for gameplay and puzzles). Either way, it's very cheap at the moment. If you have a friend who owns the game already, I would Defiently ask to borrow it first and play around, see how you like it, but that isn't nesecary.
