When someone plays a table-top game they must create a character for their game. However, some one shots will have pre-made characters, but we are going to focus on player made characters today. Most DMs will ask for a back story for these characters, this allows for the player to think of what it is that their character has done throughout their lives in the game world. This allows for a player to begin to understand their character.
Some may wonder, “If someone created a character why do they need to understand them.” While it is true that the player does make the character and therefore the player should know everything about the character. However, in a vast majority of cases a player will have to wonder, would my character would do this or how would my character react in this situation. There are also plenty of times were a character will end up going in a completely separate direction from the player’s initial goals.
