In several games, such as Monkey Island 2, the story is being told by a narrator who has just experienced it. However, their account usually seems completely truthful. What if the person were ridiculously boastful, or lying in order to cover something up, or just plain stupid?
Here's an example: Suppose we have a story which takes place in a fantasy setting, with three main characters: a boastful knight, a lying thief, and a rich twit. When controlling the knight you would be invincible in combat, irresistible to women, and a natural leader. The thief would be endlessly charitable and self-sacrificing yet somehow manage to become wealthy while all of his enemies end up dead. The twit would do things which are completely nonsensical, with equally nonsensical results. By the end of their accounts their three stories would converge with them all taking part in the same pivotal event.
