Just a collection of random stuff. I'd say if you've played the game more than a few hours, none of this is a spoiler (although, honestly, I don't think any of them are, with the exception of the labeled ones. These things are mostly just my random thoughts about the game).
1. There are true-to-life constellations in the night sky. Specifically I see Orion. I dunno too many but I know that one when I see it.
2. Miyamoto sure seems to have a thing for water lately.
3. I also think he's been watching some Miyazaki films. The little forest-y creatures seem inspired from Princess Mononoke.
4. Found a nice way to exploit the travel lengths, but it requires a Wavebird controller. You set your ship in the direction you want and hold the controller in that direction (probably "up" in most cases, since you want to maintain the fastest speed). Once you are in this position, turn the controller off and on quickly. When it turns on, the control stick's neutral position is fully in the "up" position, meaning you can put the controller down and your ship will maintain speed to your destination. Of course, be ready to pick it back up and reset it if you run into some sort of trouble, such as the octo's.
5. My GOD. The number of side quests and things to do is amazing. It rivals Animal Crossing and smashes the hell out of GTA.
6. Would have been nice, when bombing on the ship, if you could lock on, instead of having to manually aim.
7. Also would have been nice to have context sensitive item selection, meaning you automatically get different items assigne to X/Y/Z dependent on situation. For example, when you run across a fish, you should switch to bait automatically. If you slow down for treasure, the hook should come up automatically. This option could always prove a pain, so you would be able to turn it off.
8. Otherwise, allow you to setup a few customized item menus, say one for boating, one for fighting, etc., and then you could somehow switch instantaneously.
9. The game also takes a page from the Megaman Legends series, in my opinon, for a few reasons. One, the idea of a LOT of water and a few islands. I know that theme is far more prevalent in MML, but it's kinda present here too. Two, I could swear I hear some of the same sounds in WW, although it's been a long while so I could be wrong. Three, ....well I'd say it but it's kind of a spoiler, so you've been warned. When you raise the Temple of Gods, there's some markings on the outside of the tower that resemble some of the glyphics from MML, but that could just be me.
10. Why can't I ever find Beedle when I need him. I got his locations, but MAN, he's never near the islands. Super annoying. Plus, half the time he's not carrying what I need....
11. *Minor sidequest spoiler* If you talk to the "sad" girl on the steps in Windfall, you can get a sidequest to photograph something that is dear to her. She says it is perfectly round and pale. I could have SWORN it would be the moon (in full state obviously), but I was wrong. DO NOT, I repeat, DO NOT tell me what the answer is. I'll figure it out.
12. *Fairly large spoiler****AVOID**** I find it quite funny that, despite not having done the Tower of Gods, I've already gotten two Triforce Charts. Lol. Since I decided I'd rather sail around and see what there was to do, I ended up finding two of them. Haha.
13. Ok, in Windfall, the rich dood. He wants me to rescue his daughter, and if you talk to him enough, he says he'll help fund you. He then throws coins into his pots and says to find them. So I broke up the three he wanted and he got pissed. Sigh, stupid old man....
14. *Minor sidequest spoiler* I did the Flying Birdman competition. I eventually got 263 feet/yards/whatever. I wanted to see if I could get anything else, so I did it again. I ended up hitting my banner and fell down, but it still credited me with beating my old distance, even though it says I went 260. GG game.
15. *Minor spoiler* I swear the magician enemies are Toucan Sam. And I find that sad, because I'm killing TOUCAN SAM.
Guess thats all for now.
