Not sure if ANYONE other than me has played the game, I've never encountered anyone who has but, for me the worst Ending of all time came from a great Game that was released at roughly the same time as the first Fable game.
The game was Sudeki, an action RPG that should have redefined the genre, multi character control during battles, high speed fun combat system, skill and strategy based boss battles, the game was awesome and looked pretty good for it's time, despite it's 'unique' art style.
However the ending was the most horrible thing I've ever encountered, you play through the game having fun get to the half way point, oh I'm sorry I mean the part right before the final battle, you face off against the last boss in an epic and difficult final boss fight, there is a cool cut scene of him being taken down for good and...... A brief poem is said one shadow puppet pushes over another and credit's roll! I shit you not!! One shadown puppet pushes over the other and game over, that's it nothing is resolved for any characters you don't get any closure about ANYTHING, nope, two fucking puppets one knocks over the other and credits.
