Mind games can also be a tool for character development. A character who is good at mind games might be seen as intelligent and cunning. As the story progresses, the way they play mind games can change, showing their growth or downfall. In a free novel, this can be a great way to show the evolution of a character over time.
Mind games can create suspense. When characters are playing mind games, the readers don't know the outcome. This keeps them on the edge of their seats. For example, in a mystery free novel, if the detective and the criminal are engaged in a battle of wits, the readers will be eager to find out who will win.
