"Fable III" is an open-world adventure game in which the player must take on the role of the heir to the throne. During your adventure, you will earn Guild Seals, which unlock chests containing upgrades, weapons and other useful items for the long road ahead. In "Fable III" there is a glitch that allows you to obtain an infinite number of Guild Seals.
