Fable 2 tried to keep most easter eggs out of the game. But, if you played fable 1, the lady who guides you around the entire time in the beginning of fable 2, is the main character from the original Fable's sister.
Also, in a certain outfit, with the right kind of sword and gun, you look an awful lot like the male antagonist from the movie "Beauty and the Beast".
Just thought I'd like to ad: I love this game!
Also, if your bored, do something mildly absurd, like have 20 children with 4 different wives and 2 husbands or something. Buy a bunch of houses just so you can smash them up. Earn all of the achievements? (Just throwin' answers at you, sorry =D)
