Quitting a game before it’s completed is actually not easy for the easily influenced human brain to do. Self-determination theory is a driving force behind mission completion, and therefore game completion. People engage in voluntary behavior (like play) to the extent that it scratches three psychological itches:
- The need to feel competent at what you’re doing (Competence)
- The need to feel like you have meaningful choices when deciding how to do it (Autonomy)
- The need to feel connected and related to others in the process (Relatedness)
