I have to say that the wind waker is mine.
I'm sure the fact that I really loved OOT, for some reason never managed to play MM, and then just waiting for the GC's first zelda, thinking about it daily, finding out as much as I could about it daily did quite a bit for me in terms of memories. This was back when most of my information came from magazines and I could only watch say 5 clips of video from the Japanese version a day, that I found on a site called IGN haha.
But just the character that game has is great. It just feels great. While say TP may have been a huge epic, and it was great, it wasn't anything to stand out. WW was, which is why it still stands out in my memory today.
People complain of the sailing, and I'm sure when you're just trying to blast through the game those few minutes sailing can be very boring. But when you're just relaxing with the game, slowly exploring its world, coming across all sorts of things in its charming sea... It's just really nice imo. The whole feel of the game is great imo and I love it.
I only actually played it once for some reason, when it came out and I have no idea how I'd feel if I played it now, but the first experience is the one that says the most and that one experience was the one that stands out most in my mind.
Also, once you have your hands on the game, the wait for it official finishes. All you have to do is play it through to your hearts content and then that's it, it's over. Never again will you not know of that game and have to wait to play it.
The wait to play such huge games plays a huge part in the actual experience of it imo. Just looking forward to it, wondering about it, for months, maybe years. In this time all you can do is wonder and wait. It's quite a magical time really, but once you have it, that's it, that time of waiting for that game comes to an end, which is very saddening in a way. You have a new, great partner, but you've just lost the one you knew forever (or close enough) and they'll never come back. Never again will you experience the same thing for that game.
