Okay, I did 4 demos of the game on Saturday at the LGS
First demo, he did not like the game play. (he prefers buckets of dice) But he was interested in the fluff, which says a lot.
Second demo was just the opposite. He liked the system, but the background does not have enough "Grim Darkness" for his tastes.
Third demo, went well, he liked the rules and background.
Fourth demo was the best. He loved the background, and spent a good portion of the evening reading my book, he also LOVED the game play. he commented that it was simple to learn, but he could see the depth that the skills and abilities would bring in.
All told it was a decent demo day.
