GOT has some good potential...but if you are worried about code, this is one you may be disappointed in. I mean, the books aren't finished being written yet...who knows when they will get done? IMO, It will take at least 2 more books to complete the story and I don't think they will still be working on code by the time they complete these books (unless GOT pinball is produced much further down the road).
So if you don't mind that GOT pinball doesn't follow the entire story line or you don't mind Stern making up their own ending then ...fill your boots.
Who knows, they may get the dragons right on this one.
