16. According to the chapter, the best single test for whether a reward system is enhancing or replacing engagement is:

a) Fixed-ratio b) Variable-ratio c) Fixed-interval d) Variable-interval
19. In the progressive project, why are AchievementSystem and XPSystem recommended to be implemented as autoloads with signal-based communication?
a) Because it makes the code easier to write b) Because signals are faster than direct function calls c) Because it decouples the tracking logic from UI, allowing UI to change without affecting the core systems d) Because Godot requires all singletons to use signals
20. Which of the following is the best example of an ethical achievement, as described in this chapter?
a) "Play the game for 1,000 hours" b) "Open 5,000 chests" c) "Complete the game on the hardest difficulty" d) "Drink 50 potions in a single combat"
Answer Key
1. b) Variable-ratio. Variable-ratio schedules produce the highest response rate and the greatest resistance to extinction. This is why they dominate slot machine design and loot-based game progression.
2. a) Fixed-ratio. The post-reward pause is the distinctive signature of a fixed-ratio schedule. The player knows they must perform the same count again before the next reward arrives.
3. b) Autonomy, competence, relatedness. These are the three psychological needs identified by Deci and Ryan's Self-Determination Theory. All three are supported by good game design in different ways.
4. c) The overjustification effect. Lepper and Greene demonstrated that expected rewards reduced the intrinsic motivation of children who had previously enjoyed drawing without rewards.
5. b) A player who enjoyed casual puzzle-solving loses interest after an achievement system rewards each solution. This is the overjustification effect in action --- the external reward has replaced the intrinsic enjoyment as the justification for the activity.
6. c) The cognitive tension created by incomplete tasks. Zeigarnik's original finding was that waiters remembered incomplete orders but forgot completed ones, reflecting the mind's tension around open tasks.
7. b) Loss aversion. The streak-reset mechanic exploits the psychological principle that losses feel roughly twice as painful as equivalent gains, shifting the player's motivation from "earn the reward" to "avoid losing the streak."
8. d) Integrated regulation. In Deci and Ryan's framework, integrated regulation is the most internalized form of extrinsic motivation, where the behavior aligns with the person's broader values and identity.
9. b) Because players calibrate their behavior to the relative XP payouts, so the ratios communicate priorities. The XP economy implicitly signals what the designer values. Players adjust their play styles accordingly.
10. c) Artificial scarcity paired with monetization. The game could allow continuous play but chooses not to, creating an arbitrary gate that money can bypass.
11. b) The ongoing need for rewards to escalate in order to sustain the same satisfaction. Power creep is the structural logic of long-running reward-driven games: yesterday's reward becomes today's baseline, requiring tomorrow's reward to be larger.
12. b) A player grinds through tedious content they don't enjoy to complete the achievement list. The 100% curse describes the compulsive completion drive that can overpower actual enjoyment.
13. c) Transparent random drops with clearly published rates. Transparency is specifically what distinguishes ethical random reward systems from exploitative ones. The other three are dark patterns identified in the chapter.
14. a) A conditioned stimulus through operant conditioning. The coin sound is paired repeatedly with a small reward (a coin) and becomes a reinforcer itself through classical and operant conditioning principles.
15. a) Level 1 (Pure Intrinsic Enjoyment) to Level 3 (Extrinsic-Intrinsic Blend). These levels represent ethically sound design targets. Levels 4-6 represent increasingly compulsive and exploitative design.
16. b) Whether the player would still want to play if the rewards were removed. This is the central diagnostic the chapter recommends. Rewards that enhance a genuinely engaging game pass this test. Rewards that substitute for a boring game fail it.
17. c) Extrinsic reward accumulation toward more intrinsic mastery-demonstration. The auction house emphasized acquiring gear through market interactions. Greater Rifts shifted the endgame toward demonstrating skill at scaling challenges, a more intrinsic form of motivation.
18. d) Variable-interval. Notifications arrive at unpredictable time intervals. This is why checking behavior (pulling out your phone, refreshing feeds) persists so durably even when notifications are often absent.
19. c) Because it decouples the tracking logic from UI, allowing UI to change without affecting the core systems. Signal-based communication lets the UI evolve independently of the tracking logic. This is good architecture --- the UI will change many times, but the core logic should be stable.
20. c) "Complete the game on the hardest difficulty." This achievement rewards a meaningful player accomplishment requiring skill and commitment. The others are grind achievements (endurance rather than skill) or pointless tasks no player would naturally perform.
