Key Principle
Resources split into context-free (stable value regardless of game state, motivation drivers) and context-sensitive (value fluctuates with game state, situational drivers). Calculated value formulas expose hidden dominance between options, but equalizing cost-to-increment ratios perfectly is an anti-pattern — it collapses choice into cosmetic preference. The fix is asymmetric differentiation across dimensions. (Chapter 10)
Why This Matters
Without the context-free/context-sensitive distinction, designers cannot predict how resource value will shift during play. Easy direct access to context-free resources collapses the entire strategic space. Without calculated value formulas, hidden dominance stays invisible — one option is strictly superior but the designer never notices. Yet perfect mathematical balance produces strategic flatness where no choice feels meaningful.
Good Examples
- Context-free vs. context-sensitive: In Family Tree, individual happiness points are context-sensitive (value depends on distribution among players), but tree growth is context-free and collectively earned — protecting the collaborative design goal. (Chapter 10)
- Cost-to-increment analysis: A mattock (+3 stones) vs. pickaxe (+2 stones) at the same cost curve is immediately exposed as strictly dominant. Adjusting the mattock's base cost to 8 and increment to 3 nearly equalizes ratios — but creates the Perfect Balance Trap. (Chapter 10)
- Condiments heuristic: "Some variety lets players tailor experience to taste. Too many options create anxiety and ruin the experience." Select context-sensitive resources that complement the core; leave the rest out. (Chapter 10)
Counterpoints
- Perfect Balance Trap: "Perfect balance tends to be a boring experience and takes away the meaning of choice." When ratios equalize completely, options become interchangeable skins with no consequence. (Chapter 10)
- Players as irrational actors: "Players make economic decisions in games just as they do in real life, which is uninformed, intuitive and irrational." Obsessing over mathematical perfection rarely pays off. (Chapter 10)
- Over-adding resources: "As a general rule of thumb, more resources always mean a more complex economy." New resources are justified only for feedback loops or genuinely new strategies. Default: reuse existing resources in new roles. (Chapter 10)
Key Quotes
"Perfect balance, such as in this example, tends to be a boring experience and takes away the meaning of choice." — Yvens R. Serpa, Chapter 10
"If you happen to make a game that has sparked that much interest in someone to have them get in-depth knowledge of it, then you just won!" — Yvens R. Serpa, Chapter 10
"Changing the context-free resource used in the calculi helps to ground the discussion on simpler and more meaningful terms." — Yvens R. Serpa, Chapter 10
Rules of Thumb
- Context-free resources are the gravitational center — protect access to them from being too direct
- Context-sensitive resources drive negotiation and strategy shifts; their value spikes under specific conditions
- Use the most meaningful context-free resource as the unit for calculated value formulas
- Three alternatives to perfect balance: cross-resource costs, mechanical differentiation, progression gates
- Narrative justifies remaining imbalance so it feels purposeful rather than arbitrary
- Six sources of perceived value: utility, rarity, experience, curiosity, personal attachment, preference
- Perceived social value (cosmetics, identity) and perceived economic value (utility, relations) use different levers — don't conflate them
