Yet more than a third of the buyers completed the game ... 

That's a higher portion than quite a few games out there that are deemed execellent by critics ... 

It's because the internet sucks and is just filled with people desperate to complain about everything because they can't see from different points of view and accept different opinions.

That's why Zelda is divisive. They'll look at Skyward Sword and be like "oh my god, it's linear and has no interesting overworld, IT SUCKS." or looking at Twilight Princess they'll say "it's Ocarina of Time remastered, where's the originality? THIS SUCKS.".

It's just how the internet is. Personally, I always try to look at the positive side of things, so I'll always be far more enthralled by what a game does right than I would be bothered by its flaws. That doesn't mean I'll love terrible games and stuff, but I can understand what each different Zelda game brings to the table, accept them for what they are, and recognize how excellent most of them are.

I didn't said it was a bad game. I said is the weakest Final Fantasy.

By far.

Sales are no means to determine satisfaction, though. Twilight Princess sold a lot better than Skyward Sword because it was a launch title for the Wii, which was an enormous fad at the time, and didn't require the MotionPlus.

I thought FFXII was the weakest entry because of it's borefest inducing combat system and pointlessly big and over designed world ...
