3d zelda > 2d zelda any day of the week
ocarina is one of the most influential games of all time. after it came out everyone started looking after it for ideas, particularly when devs were just getting used to 3d game development.
game has masterful game design, particularly in the late dungeons.
Whatever your feelings on the game doesn't take away from the impact it had on the industry and the future of game development. People concentrating on ______rated are idiots, anyways, especially with genuinely influential games like Zelda: Ocarina of Time. Even as a Mario 64 hater, I think that game sure as fuck deserves a good amount of the praise it gets, so why do people who don't like OoT much have to go on and on about how it's "overrated"?
You want a truly overrated game, try something that's mediocre and is propelled as genius incarnate like Killzone 2 or as Oscar said, Uncharted 1.
The majority of OoT detractors come off as attention starved contrarians. People don't and won't ever agree with everything, but if your sole argument is that the game is overrated and you're really only doing so due to the sheer amount of love the game has, you're a flat out tool.
And on that note, Chrono Trigger probably is another game that has similar treatment. Maybe we CT love it a bit TOO much, I don't know, but I'd say the MAJORITY of the accolades thrown at CT are well deserved.
