Short Answer
16. In 2-3 sentences, explain why "more content" does not always mean "better world" in open-world design.
17. Describe one scenario where fast travel would damage a game, and one where it would help. Be specific.
18. Hollow Knight and Elden Ring both have worlds praised as "vast" despite being very different in actual size. What design property do they share that produces this feeling?
Applied Design Problem
19. You are designing a hub world for a game with six levels. The player should play the first three in any order, then must complete a "mid-game ritual" level, then can play the final two in any order. Describe:
- The shape of your hub (layout, how it might evolve mid-game)
- How gating works (what blocks access to the ritual level; what blocks the final two)
- Whether fast travel exists, and under what constraints
Provide a diagram or described topology. Write 300-500 words.
Answer Key
1. B — Hub-and-spoke is a structural pattern, not a technical implementation or algorithm. A central location connects to branching content areas.
2. B — The density problem is about attention and meaning, not technical limits. When every encounter is one of hundreds of identical encounters, no single encounter matters.
3. B — An ability gate requires the player to have a specific capability (double jump, fire sword, etc.) before they can pass. It is distinct from a key gate (requires an item), a story gate (requires narrative progress), or a skill gate (technically passable with enough skill).
4. B — Metroidvanias are built on the loop of hitting gates, finding alternate paths to get abilities, then returning to pass the original gates. The same physical space changes meaning as the player's capabilities grow.
5. B — Hard locks are designed to be impassable without the correct ability/key. Soft locks can be bypassed by skilled players, enabling sequence-breaking in speedruns and advanced play.
6. B — The strongest argument is that fast travel shrinks the felt world. Technical difficulty and player preference are weaker arguments; player preference varies, and technical difficulty is usually solvable.
7. B — The Ubisoft formula is recognizable across Far Cry, Assassin's Creed, Watch Dogs, Ghost Recon, and other titles: towers unlock map regions, revealing collectibles, outposts, and side missions as icons.
8. B — Handcrafted worlds provide designed, memorable content but are finite. Procedural worlds provide variation at the cost of recognizably templated encounters.
9. B — Authorship density is about how many bespoke designed experiences exist per unit of world area. Elden Ring is high authorship density; a game with many procedurally-generated caves is low density.
10. B — Time-to-interesting measures how long traversal feels empty. Dense worlds have low time-to-interesting; sparse worlds have high time-to-interesting.
11. B — The mental map is the cognitive model the player builds. It is not the in-game UI map; a good world produces a strong mental map even with no UI map at all.
12. B — Distinctive landmarks (Hyrule Castle, Anor Londo) orient the player and anchor their mental geography. The other options either do not help (fast travel) or actively damage mental mapping (linear sequencing removes the need to form a map).
13. A — Spatial coherence requires designing the connectivity graph before the art. Dark Souls' famous interconnection was planned before individual areas were built. Most games design areas first and connect them after, which produces a patchwork without coherence.
14. B — A shortcut's value is primarily cognitive. It changes the player's model of the world: what was far is now close, what was separate is now joined. The time-saving is a side effect of the geometric collapse.
15. B — Home bases invoke ownership. Players water crops, arrange furniture, feed pets. This emotional investment distinguishes them from hubs (which are functional but not owned).
16. Sample answer: Every moment of a player's attention is finite and valuable. When a world has hundreds of identical collectibles or hundreds of templated caves, each individual discovery is diluted — the 100th chest is no longer interesting. A smaller world with higher authorship density (every encounter is bespoke) produces more memorable, meaningful play per hour. "More content" produces longer playtime but not necessarily better experience.
17. Sample answer: Fast travel would damage Death Stranding, because traversal itself is the core mechanic — the game is about the act of getting there, and instant travel would remove the game's entire point. Fast travel helps Skyrim, because the map is large, players often need to return to previously-cleared areas for specific reasons (selling loot, completing quests), and the traversal between those visits offers diminishing returns after the first walk through.
18. Sample answer: Both have high authorship density and strong spatial coherence. Every encounter is bespoke rather than templated, and the geography connects in meaningful ways that reward exploration. The feeling of "vastness" comes from interesting-per-step, not from raw map size. A dense 20-hour world can feel larger than a dilute 100-hour world.
19. Rubric for Applied Design Problem: - Full credit (10/10): Hub is described with layout and evolution; three gates correctly placed (initial three levels accessible, ritual level gated by completion of all three, final two gated by ritual completion); fast-travel decision is justified. - 8/10: Hub and gating described adequately but topology is flat; fast-travel decision exists but is not well justified. - 5-7/10: Basic structure present but gating is ambiguous or missing one layer; hub feels generic. - Below 5/10: Treats the problem as linear rather than gated; hub-and-spoke structure absent.
Key design choices that strengthen the answer: - The hub physically changes mid-game (new wing opens, NPC arrives, statue crumbles) - The ritual level's gate is thematically reinforced, not just mechanical - Fast travel, if present, is gated on first-visit to each level (never available immediately) - The topology is described as a graph (adjacency between levels) rather than just a list
