I haven't played Fable 3 but from axillary evidence it would be reasonable to conclude it was hardly 'freaking awesome'.
Anyway ok fine since you demand it I'll spell things out more clearly.
I'll use Fable 2 as my reference since it's the last Fable game I played. I enjoyed the game at least for the most part until it got to the epically bad ending. What annoyed me about that game were all the side experiences they choose to focus on instead of filling out the core experience more. The entire relationship/marriage mini-game was emphasized both in game and in many pre-game interviews to the point where it really added nothing to the core game itself and due to the diverted resources detracted from what you wanted to play. So instead of having a shallow and meaningless courtship side mission they could and should have focused on having more meaningful and interesting characters in the world. The 'working' mini-games and the property system were an interesting way of accruing wealth but then they neglected to including meaningful gameplay reasons for actually getting money since you could get the best weapon less than half way through the game. So that just became a wealth creation cycle completely separate from the core experience.
I guess what I am trying to say is that Lionhead have kind of forgotten the core values of games, AAA or casual, and that they have increasingly focused more on the superficial.
