I totally screwed up in The Wind Waker. I missed a ton of items that I may never be able to get again, I'd probably need to spend five hours at once just scrounging through the different islands looking for treasure, etc.
So I deleted my save, bought a strategy guide on Amazon.com, and will try to play through the whole game (start to finish) with it. I usually hate using strategy guides, but I think if I really want to finish this game during the summer (or even the early Fall), it's necessary to have one.
