This adventure has great replay value, because the previous Season 3 Tier 2 adventures that the players have gone through before it influence the kind of experience they will have, and all of the options make it so that you can run it twice and it'll be like you have ran two different adventures. It's like purhcasing several adventures in one, very nice ! The writers have put a good effort in roleplay perspectives -- the corrupted dragon, the imperfect galeb duhr, the overly-perfectionist stone giants. As I always say, it's not rolling dice that'll make for memorable experiences, but the unusual stuff like this that'll make you, several months later, remember the adventure in your heart. It's not the easiest adventure to prepare, but gives a very nice satisfaction to the players when they've assembled a nice army against Evil, making the end fight almost like a movie scene. I recommend the purchase of this adventure.
