I gotta give it 4 stars.
It was a great story that took about 6 hours of actual game time. It included Mass Combat, Social Combat, crime scene investigations, Fair Folk, Death knights, etc.
All in all it was exciting and fun to play, my only complaints are that it didn't include any new info at all, no artifacts, no canon, no nothing.
Also it didn't include any special rewards for completion, which isn't all that bad because it's up to the story teller but still...
I strongly recomend this product to any ST who wants to introduce the guild or just take a night off from writing his own story.
