This doesn't always need to be done.
Fans complained about tear collecting and stealth sections, even when Nintendo reused them constantly. But they finally perfected this design in SS, and so far no one seems to be complaining about it.
When I call these games **** I am insulting them...
On an HDTV:
-turn off all enhancers
-set brightness slightly lower, but color and contrast higher
-set sharpness to 0 or as low as you like
This should make the game look better.
People are ignoring the positive changes and superb level design in favor of complaining about nitpicks, complaining with a lack of information and catering to more subjective ideas like better graphics. It's Nintendo's fault that they have a weak system but SS would have looked just as much...
Yes, you can, but I recommend getting the Hylian Shield so the other three become obsolete. You can't get the HS until much later in the game, though, and you have to fulfill a challenge given to you by the Thunder Dragon (not telling what it is, find out for yourself. ;) )
Have you fought Demise? Everyone I know has said he is between extreme and moderate difficulty. Listing the strategy to beat him doesn't make him sound easy.
