Start paying someone for their hobby and watch them stop enjoying it -- external rewards poison intrinsic motivation.
The overjustification effect occurs when an external incentive (money, points, rewards) decreases a person's intrinsic motivation to perform an activity they previously found inherently enjoyable. In gaming, it explains why daily login rewards, battle passes, and achievement systems can actually make games feel less fun over time. When you play a game because you want to, the experience is self-rewarding. When you play because you 'need' to complete the daily challenges, the game becomes a job. The external structure replaces internal motivation, and if the rewards ever stop, the activity feels pointless -- even though it was inherently enjoyable before the rewards existed.
Example
Players who genuinely loved Destiny 2's gunplay report that daily and weekly challenge checklists turned the game into a chore. World of Warcraft's push toward daily quests and weekly resets made many players feel obligated rather than excited to log in. Indie games without reward treadmills (like Celeste or Outer Wilds) are often described as more 'purely fun' because nothing external competes with the intrinsic joy.
Why it matters
The overjustification effect is a critical warning for game designers: adding rewards to an already enjoyable activity can backfire. It explains why some of the most beloved games have minimal extrinsic reward systems and why live-service burnout is an industry-wide problem. The healthiest engagement comes from intrinsic motivation, not reward schedules.
