Fabled
When you're promised a golden goose and end up with a broken egg. Fabled comes from the game Fable, which had a guy named Peter Molyneux who promised the moon and delivered a pile of crap.
I was promised a dragon companion. Got a chicken. Fabled.
This game was going to be the best ever. Now I'm stuck with a broken sword and a sad face.
Fabled is like getting a pizza and it's just bread with ketchup.
