You know, I think OoT was great, but I do tend to nitpick at multiple aspects of the game. For now, though, I'll only poke at info:
I think what really bothers me is how Nintendo gives us a smidge of information and then neglects to tell us anything for a decade or more. For instance, the whole "reincarnation" thing really became popular after OoT's release because of the Gossip Stone that said that Kaepora Gaebora is the reincarnation of a sage. So, people suddenly assume that Link reincarnates... when, to my knowledge, there has never been any confirmation of that. In fact, it's beed stated over and over that Link is different almost each and every time. ANYWAY! They told us that KP is reincarnated... well, of who? In TWW, we learn that there are other types of sages, so who was Kaepora Gaebora a reincarnation of? THEY NEVER TOLD US. It bugs me to this day.
On top of that, they go into mentioning the Sheikah. The Sheikah guarded the royal family, blah blah blah, and only a few remain. Pretty much in secrecy, I might add. I want the details of this race. I want to know how they came about their skills, exactly what happened to them, and so on and so forth. I mean.... why did they serve the royal family and become the shadows of the Hylians? I want more detailed information about them, especially since they seem so important.
And what about religion? Everybody in Hyrule seems to know of Din, Farore, and Nayru, but some races have their own gods. For instance, Jabu Jabu is the Zora's god. The Gerudo have the Goddess of the Sand... Do these idols have any power? Are they false idols? Are they similar to the spirits in TP? Tiny bits of information like that really get to me, because I feel that detail is important.
And lastly.. is Link really that dense? I mean, c'mon, he was dropped off in the Kokiri Forest as an infant. He had to grow. Surely, even at 10 years old, he'd recall something about growing up. Did he just never realize it? Or maybe he couldn't because the Kokiri might start out in a body that appears very young, and it stops growing at a certain poing. We know that The Great Deku Tree gives life to the Kokiri, but since they don't grow up, are they automatically made to look like that, or do they start a little younger and grow only a little bit? How long is their lifespan? WHY DON'T WE KNOW?!
I know, I know... the information isn't necessary, but over the years we've seen more and more development, and I think if Nintendo would just give us a little more information, then it'd make understanding some aspects of the series a whole lot easier.
