Just completed this and have to say I felt dissapointed.
I enjoyed the previous 2 Fable games, bit this one felt very 'over-streamlined'/over-simplified. Fable has always been about making the RPG more accessible, but I think Fable 3 really has gone too far. A lot of the choice and freedom had been toned away, to the point you can't even do various things anymore unless the game prompts you too (expressions etc), and the choices at the end whilst being kind where laughably overtly good and overtly bad, not to mention not really that satisfying. The story also wasn't much to write home about in the scheme of things, and there was some shocking lack of continuity (Reaver as one example... both in comparison to Fable 2 and also within the game.)
Also extremely easy, I got the no knock-out achievement first playthrough, and I was playing this whilst sick so not exactly at the best point of my concentration cycle.
Then on top of that the frame rate was extremely poor (even after the patch), the blur effect should simply have had an option to be turned off ala Mass Effect. I could go on.
Not a bad game per se...but I was expecting a lot more, the game has been simplified too much, and has far too many flaws. The games main saving grace was the voice acting which was once again pretty decent, and the humour if you liked the cheesy style.
