Tyranny review: Obsidian's RPG ponders the nature of evil

Imagine a world in peril. Kyros, the overlord, dominates everything in the known world--except for one tiny realm, that is. Known as the Tiers, this last bastion of goodness, of freedom, holds out in the face of impossible odds. Armies clash, and Kyros's overwhelming forces handily dispatching the desperate populace until all hope seems lost. In a normal video game, this would be the point where your untrained, unskilled, and unknown Joe Nobody enters the picture to save the day, to beat back the tides of darkness, confront Kyros, and eventually defeat him.
