The Storyteller System is designed around the concept of “roleplay first.” Created by White Wolf, Inc, a group that is now a part of Paradox Entertainment, in 1991, the system design showcases a focus on narrative development and simple task resolution. When creating a character using the system, you design a merit, something the character strives towards and can provide boons, and a flaw, something that the character struggles against and can provide banes. By making roleplay choices aligned with these, the character will gain boons or banes depending on how they act. 

Part of what makes this system great is how easy the character creation process is. It contains enough complexity to allow for fun build options, but is simple enough to not overwhelm the player with too many options and descriptions.
