Personally I for one would also never give a remaster or remake (a straight forward one at least) a score as high as the original. Simply due to the fact that no matter how much work has or has not gone into something, it’s just not new. And making improvements and modernizing things is just not really impressive. I wonder why those are even given scores at all actually, because they hardly reflect the real quality of a game. I think it should be taken more as a score about the quality of the improvements and changes.
For these Zelda ones in particular, jury’s still out on Skyward Sword obviously because I haven’t played it yet, but Majora’s Mask was made worse because of the changes to the bosses and save system and Twilight Princess wasn’t really anything more then a port with a resolution bump which was disappointing. The Wind Waker was an improvement though but that one started off the weakest of the bunch. Ocarina of Time was exactly the same except for the boot equipping which was fine because that game was already perfect. The fact that Ocarina was still given a score as high as it got, only a couple points under the original and higher than nine out of ten games that are actually new, probably speaks volumes about how good it is.
And yes this was a post made to once again rub it in that Ocarina of Time is perfect.
