The problem that I have with OOT is that it seems to be the guild that is used to judge all of the new Zelda games.
I think that seems to contribute to the whole "overrated" deal. When a game is so persistently compared and used as a sort of "bar-line", for new and up-coming games, I feel it takes away from both games.
Especially after the third or more time....
I feel this especially with games like Wind Waker and Twilight Princess. Both are so different from Ocarina of Time, that I don't feel it is quite right to compare them in such a manner. Whereas comparing stories and gameplay, I have no problem with, I think that their differences should be taken into account, rather a single game set the standard.
