I'm hoping there might be someone out there who can give me an answer.

I haven't read the books or watched the show yet. I've been meaning to read the books for a few years now, but I don't buy books a lot, given what they generally cost here... Not the point. Haven't read yet. Would like to though. Can probably find someone to borrow off or I'll splurge a bit... Again, not the point.

As for the show, well, I've got it, but I haven't watched it yet for a simple reason. I'm not sure which to do first. So I'm trying to find people who've done both and see whether they'd suggest reading the books or watching the show first. Or telling me it doesn't matter is acceptable too. Because as much as I want to watch the show, I'm wondering if that'll in anyway negatively affect my impressions of the books.

Wow, that was a long way to ask a short question.

tl;dr...
Game of Thrones - Books or show first??
