I am STILL terrified of all the forms of Zombie/dead things in Zelda. Oot, MM, WW, not so much in TP, but still a little too much for comfort.
I didn't work out how to use the sphere grid until I was a least in Bevelle. I distinctly remember having 41 levels for someone when I first used it properly.
On a tangent, I always do that in FF games, just lose interest right before the end, but then I'll get back into it a few months later and realise how under-levelled I am. Except in IX, I lost interest about 2 hours in, tried again a few months later and couldn't put it down.
