ghoulish isn't it. i want George to finish the series, but only for himself. i think you can always tell the difference between people who do create and people who don't when future ASOIAF books come up. people who create seem to better understand that sometimes big projects can't be tied up.
people who make stuff will know how much it's (probably) hurting him that he's not yet been able to nurture his baby exactly how he originally wanted. people who don't make stuff just want more content and don't understand why they can't just be given the bullet points of the plot immediately.
it's like, do you want future ASOIAF books because you love George's writing and want to swim in his world, or do you want future ASOIAF books so you can immediately skip to the end of Winds on release day and find out if the Others broke through the Wall with a horn.
