After Alttp, they really start going down hill(slowly though, not super fast like the FF games post FF 7). While technically by default being 3D shouldn't take away from the Zelda games(as the genre is well suited for either), they failed to impliment it good enough to not hurt the game play. Then there's the fact that the Zelda games seem to get increasingly easier, which aside from Link, the Zelda games weren't that hard to begin with(although in the old days, when I played Zelda, Zelda was super hard as well, man those were the good ol days).
