I recently acquired the 2nd Edition of A Game of Thrones: The Board Game. I've played the older edition for years.
I'm having people over to play the new version later today, many of whom are familiar with the old version, but I haven't exhaustively read the new rules yet. I noticed in the quick reference sheet that there are minor (but important!) rules differences, such as how the Star Raid order works.
What rules changes have there been since the first edition and its expansions?
