Re: Sources and Potential Sources for and of the Giant
Well, we know Monkey Island is not a source; IIRC we have Word of Giant that he'd never played any of the series. When the Dashing Swordsman class first appeared, lots of people (myself included) said "Pun fighting! You fight like a dairy maid!", but it turns out to be just one of those strange coincidences.
I'm really not seeing any inspiration from Sword of Truth (which I liked, but would never have called "highly preplotted": at times it really felt like the author was making it up as he went along) or Honor Harrington (which I love to bits, but is best described as "Hornblower in Space": the battles are completely different to anything you see in OotS).
