I like the idea of a Fable Prequel. Having sequels is all well and good, but I much prefer the Mid-evil Era of the original over the Industrial Era Fable 3 is in. Seeing the Heroes Guild in it's prime in Nostro's time would be cool. Could that be in the question?
I also would like the question previously posted to be asked: What is your thoughts on the fans criticisms of the last 2 games in comparison to the first, how are you planning to go about the next installment? And is Scythe going to return in the next game like the previous two keep hinting at?
EDIT: Just like the post before mine, I would really like to see a Jack of Blade's robe to go with his mask, as it doesn't look right without.
