A. Either change the time period it's set in, or get the **** out of Hyrule. The only thing I liked about Majora's Mask was the fact that it WASN'T in Hyrule, because I'M FUCKING SICK OF HYRULE. Also, that was one of the reasons I loved Wind Waker.
Considering the locations change and don't have any real comparison to other games, this complaint is moot...
B. Voice acting, dear god. It's 2008, and may very well be 2010 by the time the next Zelda comes out. There is NO EXCUSE for no voice acting.
Ugh, get out presentation nerd...Voice-acting is the most worthless and least important addition to any game
C. Something NEW and INTERESTING for Link. Maybe give him an axe instead of a sword, or a polearm or something. Give him a musket instead of a bow. ANYTHING.
Yeah, uh, that's what his secondary items are for? I'd rather him carry around things like this (Ball-and-chain, anyone?) in his pants...
D. On second thought, even better than C, have Link NOT be the main character. Either have him not in the game, or maybe be old and wise, and act as a sort of mentor for the main character.
WHY NOT JUST MAKE A WHOLE NEW IP!?
Begin with making the traditional Zelda puzzles more complex. Instead of just using 1 item to solve puzzles, why not create dungeons that require you to use all the items you have acquired throughout your adventure to solve...and some puzzles requiring multiple items to solve. Something more like Zach and Wiki (but not that extreme) would be nice.
I'm sure that's something the Zelda team has trouble with, considering they have to find a perfect balance in puzzle difficulty...Remember, it's not just a game for hardcore Zelda fans...
More fluid fighting. Link needs to become much more aggressive and fluid as a fighter...look at games like Prince of Persia...there is no reason why we can't have more diversity in attacks...without making the game too complex in button mashing. Also, the items need to be more flexible while attacking.
Ehhhh...I don't like the comparison to Prince of Persia, but from Twilight Princess you can see that they HAVE been expanding the combat...I'm not really sure what you mean by "fluid"...
I feel the mechanics in every Zelda game change enough that it's still worth going back and playing each and every one of them...That is, unless you think that the sailing in Wind Waker is comparable to the wolf mechanics in Twilight Princess, or that the dimension-shifting in Link to the Past is the same as the season-changing in Oracle of Seasons, etc, etc...Really the only things that stay the same are the main characters (or rather, just Link sometimes), the battling (which is still being shaken up enough to stay fresh), and the "find a new item in a dungeon to take the boss on with" mechanic, which should NEVER be gotten rid of because it's a Zelda staple...Obviously new items and environments will appear, and gameplay mechanics will obviously change a bit considering the Zelda team will utilize the functions of the Wiimote...No, Zelda does NOT need voice-acting, anyone who says so needs to just go sit their ass in front of a movie like Metal Gear Solid 4...No, Zelda does NOT need orchestrated music, midi is just fine...No, Zelda does NOT need to be set in some far-off land, considering the environments are different enough in every game ANYWAY (even if they are supposedly the same Hyrule)...
In the end, the game just needs to be fun, which the Zelda team has never had a problem doing...Looking forward to what they come up with next...
