^What do you mean (post)-
OoT, game-wise,
OoT is in no means one of the first games. Timeline wise, yes it is, and there is no way
LoZ could be before
OoT in the timeline.
Game-wise however, there're quite a few before
OoT. Just to name a few,
LoZ,
AoL,
ALttP, and
LA. Not to mention remakes, the series was around twelve-thirteen years in age by the time
OoT was released.
*sigh* A few things I have to say, okay, mainly two.
One:
SS is rumored, and strongly hinted, to take place a few hundred years before
OoT, so now it could not be New Hyrule.
Two: In
ST they discovered New Hyrule, and Hyrule was under the ocean. The tips of Hyrule peaked above the sea, and Skyloft was obviously a lot higher than a couple of mountains, which means that
ST Hyrule is New Hyrule, and Skyloft is either gone with Hyrule, was the peaks in WW, or is still in the sky.
