I don't remember that Grandma moment in Wind Waker at all, but I'm sure I must've visited home some time. Weird.
If it's one thing you never mentioned that will stick with me, it's getting Biggoron's sword. I don't know how loved that thing is outside of the circle of people I know, but for us it was the most badass thing ever. Unfortunately, it means disappointment for every future game that doesn't offer some sort of massive, two-hand sword.
Here's to hoping there's one in Skyward Sword, lol
