It's not 70 hours. I'm at over 66 hours now, but that's after beating the game and then going back and working on some side quests (although I suppose there's some time lost, because you don't save after you win). Still, it's a big, big game. It goes by fast at the end, though, because in the latter half of the game you just kinda rush from dungeon to dungeon. While the story is still good, there just isn't as much of it. I'm hoping, to some degree, that the next Wii Zelda game is a "true sequel" story-wise, because there are some loose ends.
After I beat it, I went back and replayed Wind Waker. I won't say I miss the cel shading, but I will say that WW looked excellent,
and I would not be offended if they use that style again (already looking forward to it in the DS Zelda).
The save thing? I don't know, it doesn't really bother me. Using Ooccoo helps though, definately. It works like Skry says, just be careful not to walk into the dungeon entrance, or you'll lose the "warp point" you made. Ooccoo is creepy as heck, though. One thing that does bother me, though, is that I'm limited to 3 save slots, unless I use an SD card or something. I've let a couple people play the game on my Wii, and now if I want to let someone else have their own save, I'll have to delete one. Why? Don't I have room for like 1500 more saves? Why limit it to 3?
And yeah, Hyrule Feild is a lot bigger than the OoT version. My friend pointed out that the "dry" version of Lake Hylia, in this game, has more water in it than the "full" lake in OoT.
I have no other brilliant things to say. Let me know when you've beaten it, we can discuss "timeline theory"
