I think that

sums up my opinion of Fable III so far.
I really liked Fable, and had loads of fun playing it.
Fable II on the other hand...
I REALLY didn't like some of the changes it made, but something kept drawing me in to play it. (On my friend's 360, I'm yet to buy one myself) I had fun playing it, but I felt like it had less soul. I felt like the more I played it, the more it brainwashed me into having mixed feelings about the game. It kept me entertained, but it left me with a feeling of 'Eh....'
So anyway, I hope that Fable III doesn't take a turn for the worst, and leaves most of what I love about Fable unchanged.
