a) Linear. b) Exponential. c) Logarithmic. d) Constant.

4. Vanilla World of Warcraft's 1-60 grind is cited as an example of which XP curve problem?

a) A logarithmic curve that flattens too quickly. b) An exponential curve that produced a brutal late-game grind. c) A linear curve that felt monotonous. d) A polynomial curve with no soft cap.

5. In Path of Exile's passive tree, progression is primarily delivered through:

a) A simple branching tree with three classes. b) A sphere grid walked by each character. c) A web with cycles, multiple paths, and thousands of nodes. d) Gear-based skills that replace a traditional tree.

6. The "illusion of choice" pitfall in skill-tree design refers to:

a) A tree that secretly has no branches. b) A tree that looks branching but funnels every optimal player to the same path. c) A tree where respec is impossible. d) A tree that unlocks faster than the player can use its nodes.

7. Unlock-based (Metroidvania) progression is described in the chapter as using abilities as:

a) Statistical bonuses to existing capabilities. b) Keys that open new spatial regions of the world. c) Temporary buffs with cooldowns. d) Cosmetic flavor without mechanical effect.

8. Which game is described as having arguably the most perfectly tuned Metroidvania progression system in the chapter?

a) Metroid Prime. b) Castlevania: Symphony of the Night. c) Hollow Knight. d) Ori and the Blind Forest.

9. Horizontal progression, as defined in the chapter, means:

a) The character gains raw power in bigger numbers. b) The character gains new options without necessarily getting numerically stronger. c) The character moves across a map. d) The player's skill, not the character's, is what advances.

10. A soft cap on a stat is best described as:

a) A ceiling past which no further investment is possible. b) A region where investment yields diminishing returns but remains possible. c) A temporary cap that lifts at certain story milestones. d) A cap that applies only to multiplayer modes.

11. Hearthstone's "Standard" format is cited in the chapter as a structural response to:

a) Trap builds in complex skill trees. b) Power creep across successive content releases. c) Grinding valleys in the middle of the level curve. d) Matchmaking imbalance.

12. What does the chapter call the gradual inflation of numerical scale across content releases, which devalues old content and requires eventual "squish" patches?

a) Numerical drift. b) Power creep. c) Horizontal expansion. d) Endgame collapse.

13. The chapter's recommended practical process for designing progression begins with:

a) Choosing an XP curve. b) Stating what promise the progression makes to the player. c) Laying out the ability unlocks. d) Balancing the combat numbers.

14. In the GDScript ProgressionSystem.gd example, the _xp_for_level function uses which curve family by default?

a) Linear. b) Exponential. c) Polynomial. d) Logarithmic.

15. The chapter's threshold concept holds that:

a) The best progression system is the one with the biggest numbers. b) Progression is really about the feeling of change, not about numbers getting bigger. c) Unlock-based progression is always preferable to XP-based progression. d) Progression systems should be identical across genres for consistency.

Answer Key

1. b) Player-skill progression and character-power progression. (Every game mixes the two; the ratio is a fundamental design choice.)

2. a) Near-pure player-skill progression, with almost no character-power growth. (Madeline's mechanical capabilities at hour ten are the same as at minute one; the player's skill is what grows.)

3. b) Exponential. (Each level costs a multiple of the previous, making late levels hard-won. The cost is that the late grind can become brutal — as Vanilla WoW demonstrated.)

4. b) An exponential curve that produced a brutal late-game grind. (The 1-60 grind frequently took 200+ hours, which many players resented.)

5. c) A web with cycles, multiple paths, and thousands of nodes. (Over 1,300 nodes; huge build diversity at the cost of overwhelming new players.)

6. b) A tree that looks branching but funnels every optimal player to the same path. (Happens when one branch is mathematically dominant or one node is universally critical.)

7. b) Keys that open new spatial regions of the world. (The morph ball opens narrow passages, the double jump reaches higher platforms — the ability is both combat tool and spatial key.)

8. c) Hollow Knight. (The chapter singles out Team Cherry's pacing and world design as the contemporary gold standard.)

9. b) The character gains new options without necessarily getting numerically stronger. (A new weapon is different, not stronger; a new ability offers a different tactical tool.)

10. b) A region where investment yields diminishing returns but remains possible. (Contrast with a hard cap, which is an absolute ceiling.)

11. b) Power creep across successive content releases. (Standard rotation cycles older sets out of competitive play, containing creep to a window.)

12. b) Power creep. (Its three main costs: old content is devalued; balance fractures; new players are overwhelmed.)

13. b) Stating what promise the progression makes to the player. (If you cannot write the promise in one sentence, you do not know what you are building.)

14. c) Polynomial. (xp_base * pow(level - 1, xp_exponent) — exponent 1.7 by default, a common starting point for modern RPGs.)

15. b) Progression is really about the feeling of change, not about numbers getting bigger. (The chapter's central thesis — numbers are a means of marking growth, not the growth itself.)

Scoring

• 14-15 correct: You have internalized the vocabulary and the thinking. Move into the case studies with confidence.
• 11-13 correct: Solid grasp; re-read the sections covering your misses before the case studies.
• 8-10 correct: Foundational ideas are there but several specifics are slipping. Re-read the XP curves section and the horizontal-vs-vertical section before continuing.
• Under 8: Give the chapter another pass. Progression design requires the specifics; the broad strokes alone will not carry you.

A Note on These Questions

Several questions test specific content (which game, which curve, which studio). Miss these without alarm — look them up and move on. The ones that matter are the conceptual questions: the skill-vs-power distinction (Q1, Q2), the horizontal-vs-vertical distinction (Q9), the meaning of power creep (Q12), and the threshold concept (Q15). If you missed any of those, go back before you try to apply the chapter to your own design. The framework is what this chapter is actually for; the details are tactics within it.

The most important question is Q15 — the threshold. Designers who have crossed it design progression systems that feel alive. Designers who haven't ship numerical treadmills. The difference is everything.
