Its just a shame that Zelda games now have stopped being medieval after Ocarina of Time.. well Twilight Princess kinda works somewhat, but just the atmosphere in general i feel was just so good back then!

The thing is Ocarina of Time when it was released had a rating system that was for everyone, while the new ocarina of time (Which btw looks less scary due to the graphics having a more candy eye look to it) have 12+ rating. So its basically the same game, only with better graphics, so i think its a pretty good example though in my opinion.

Yes, but the two different rating systems have different standards for what is to be for what ages.
The ESRB rating for Ocarina of Time on N64 was E, and its 3DS version was E 10+, however, E 10+ ratings came into circulation much later than the initial 5 ESRB ratings, so we don't really know whether or not Ocarina of Time's rating would've been E or E 10+, but I can assume it would've been E 10+, because people's views of video games were much more closed minded when it came to inappropriate content back then.

In terms of game ratings, though I still believe that they a have a place. I think that parents should be aware of the games the're buying for their children. Unfortunately, it seems like people nowadays are starting to care less

Edit: Although i do notice that rating system have become somewhat different with times too. Like Ocarina of Time when it first came out it was for everyone on N64 system. While now its.... 12+.
