Here are the the things that make Legend of Zelda a GREAT game:-

1. Puzzle

2. Controls and Gameplay

3. Story

4. Graphics and Game Design

5. Sound and Music

Now if you were to choose only two out of the list above, which one do you think from your own view and reasoning that is the most important department to zelda fans happy?

Tight Controls.

Puzzles, Music, Story and Graphics are put to waste without them.

what i mean is choose two from the list, how i listed them 1 to 5.

Story and Puzzle FTW!

Link and Zelda are two characters EVERYONE knows about. Casual/hardcore, doesn't matter. The puzzle aspect makes it awesome too.

If I had to choose 2, then 2 and 4.

1, 3, and 5 all into place once 2 and 4 are polished.

...I was gonna say exploration and discovery, but you didn't list that.

Lol, same here

2 and 4.

The real pull for me is that you're a small village boy who goes on a big adventure. That's the amazing part.

1 and 2 for me.

Errr for me it's the dungeons the most important aspect... that is puzles, exploration, objects and how to use them... that's both game design and gameplay for me...

though I don't thing graphics are usefull at all (afterall I love this series since the 1st one, heck I even prefer the 2D ones).
Music is important... but that's mainly nostalgia :p

So from your list i'd really pick #2 and #1 puzzles... cause I think the gamedesign should be part of this one and not #4 :p

so there that's what I like in zelda!
