IMO, just because the game was mind blowing at the time, it doesn't mean another game can be better than it to people.

Was. Not is. Every game released since is better mechanically. No one is which is the least important or or game changing. The topic asks which one is the worst. Every Zelda since improves apon what OoT started. OoT did not age as gracefully as any of the others have and will. Anyone who genuinely thinks OoT is not the worst, at least mechanically, can't let nostalgia go and it is probably the first 3D Zelda and one of the first 3D games they ever played. OoT was the first Zelda game I ever played, and even I can admit that it doesn't compare to its successors.

Skyward sword had probably the longest tutorial of any zelda game(though TP was also long).  It has the most hand holding of any zelda game, and was the most linear.  The motion controls were neat, except for the part that at best they worked 90% of the time.  The bosses(with a couple exceptions) were just terrible...nothing else needs to be said.  However, SS had probably the best puzzles of any zelda game, and had one of the best stories.  

Anyways, there are other reasons, but those are the big reasons why people do not prefer skyward sword.  I personally really enjoyed Skyward Sword, but looking back, it had some very obvious flaws that were non existent in previous zelda games.

Actually, both of those are true for me. Only, it was 9 years after release.

I haven't played Majoras Mask yet, but out of all the rest i've played, i'm choosing Ocarina of Time. Such an over rated title, and isn't nearly as good as what has followed.

When did you play OOT?  be honest, even if you take off the nostalgia goggles, most will see just how much better it is than Skyward sword or even TP.  WW and Majoras mask improved on every aspect of OT, TP and Skyward sword did not.  They were too linear, and had too much handholding.  

Even with the open-world, Wind Waker was still pretty easy and linear IMO. The only Zelda's less linear than Ocarina of Time after it released are Majora's Mask and A Link Between Worlds

You are right about Wind waker, it was easier, and still linear but there was a huge ocean to explore, and each zone had something special.  OOT you were able to do the dungeons out of order, and majoras mask had the largest amount of side quests of any of the zelda games.  And a link between worlds was amazing, but it's not 3d:P  However, IMHO the games have been getting easier with each iteration WW is easier than MM and OOT but harder than TP, TP is harder than SS...well...depending on how the motion controls were working for you SS may be the hardest of the batch (but not for the right reasons).

I was five when I played OoT, so it had to be in 1998-1999.

I am being honest. Even with the handholding and linearity they are not, mechanically, worse than OoT. Even at their worst, they where equal to what OoT currently is. TP was larger and empty, but there was still more to do than in OoT's overworld. SS was linear, but the way you explore that linearity is far more interesting and rewarding than any of the exploration in OoT. Even with the shitty motion controls and lack of camera control, combat was far more kinesthetically satisfying than that found in OoT.

Like I said, mechanically speaking, OoT is the "worst." Without a doubt. Yet I always put it as my 3rd favorite 3D Zelda, behind Wind Waker and Majora's Mask, but ahead of Skyward Sword and Twilight Princess. I think it is objectively the worst, but I think that Twilight Princess is subjectively the worst. It's the least original, the most derivative, and the most boring. 

Hopefully Zelda U can break that streak with something a little harder. I'm hoping for something between Majora's Mask and Wind Waker's difficultly, leaning closer to Majora's Mask.
