Chapter 7 Further Reading

Books

Katie Salen and Eric Zimmerman, Rules of Play: Game Design Fundamentals (2003)
The definitive academic treatment of rules in game design. Salen and Zimmerman's framework of constitutive, operational, and implicit rules (which this chapter draws from directly) remains the most widely used rule taxonomy in the field. Chapters 11 through 14 on rules, and Chapter 23 on games as the "play of meaningful choice," are essential reading for any designer who wants to understand the theoretical foundation beneath practical rule design. The book is dense and academic in places, but the rule hierarchy framework alone is worth the investment.

Bernard Suits, The Grasshopper: Games, Life and Utopia (1978, reissued 2014)
Suits' definition of a game --- "the voluntary attempt to overcome unnecessary obstacles" --- is the philosophical ancestor of this chapter's argument about constraints. The book is a Socratic dialogue exploring why humans choose to bind themselves with rules when they could simply walk to the finish line. Suits argues that the rules are the point: without them, there is no game, and without a game, there is no achievement. Accessible, witty, and surprisingly relevant to modern game design despite being written before the video game era.

Tynan Sylvester, Designing Games: A Guide to Engineering Experiences (2013)
Sylvester's chapters on "engines" (self-reinforcing systems) and "economies" (resource flows) provide the systems-design perspective on rules. Where Salen and Zimmerman analyze rules philosophically, Sylvester analyzes them mechanically --- how do rules create feedback loops, resource flows, and dynamic tension? The chapter on "elegant design" (achieving depth through minimum complexity) directly complements this chapter's argument about rule interactions and the danger of rule creep.

Jesse Schell, The Art of Game Design: A Book of Lenses (3rd edition, 2019)
Schell's Lens #30, "The Lens of Rules," asks six questions about your game's rules that function as a diagnostic tool. Lens #33, "The Lens of Meaningful Choices," provides a framework for evaluating whether your rules produce genuine decisions or false choices. The lenses are practical, concise, and immediately applicable to your own project. Keep them as a checklist during playtesting.

Papers and Articles

Sid Meier, "Interesting Decisions" (GDC 2012 keynote)
Meier's famous assertion that "a game is a series of interesting decisions" is the core design philosophy behind this chapter's treatment of meaningful choices. The keynote explores what makes a decision interesting (trade-offs, consequences, information) and what makes a decision boring (obvious best answers, trivial stakes, random outcomes). Available as a GDC Vault video and widely summarized online.

Richard Garfield, "Luck in Games" (2012)
The creator of Magic: The Gathering explores the relationship between rules, randomness, and player agency. Garfield distinguishes between "input randomness" (random events that the player responds to, like a shuffled deck) and "output randomness" (random events that determine the result of a player's action, like a damage roll). This framework is essential for understanding how rules create different types of strategic depth, and it connects directly to Chapter 10's treatment of randomness and probability.

Dan Cook, "Loops and Arcs" (lostgarden.com, 2012)
Cook's essay on the relationship between repeating game systems (loops) and one-time narrative structures (arcs) provides a useful framework for understanding how rules support different types of player experience. Rules that create loops produce replayability. Rules that create arcs produce narrative progression. The best games weave both together. This essay is a bridge between this chapter and Part V's coverage of narrative design.

Talks

Mark Brown, "How Baba Is You Works" (Game Maker's Toolkit, 2019)
Brown provides a clear, visual analysis of how Baba Is You implements rules as physical game objects. The video traces the game's design from its game jam prototype to its full release, showing how the core concept (pushable rule tiles) was refined through iteration. Essential viewing for understanding rule-breaking as a design mechanic.

Jonathan Blow, "Fundamental Conflicts in Contemporary Game Design" (GDC 2007)
Blow argues that many modern games present false choices disguised as real ones --- that the "decisions" players make are often illusory or predetermined. The talk is provocative and opinionated, and not everyone agrees with his conclusions, but the framework for evaluating choice quality is rigorous and useful. This talk directly informs Section 7.4's treatment of meaningful versus false choices.

Mark Brown, "What Makes Celeste's Assist Mode Special" (Game Maker's Toolkit, 2018)
Brown analyzes how Celeste's Assist Mode demonstrates the relationship between constraints and experience. The video explores how removing specific constraints (death, dash limits, game speed) changes the game's emotional character without changing its rules. A concrete illustration of how constraints create not just challenge but feeling.

Games to Play

Baba Is You (2019)
The most direct illustration of rules as game objects. Play at least twenty levels and pay attention to the moment when you realize the solution requires breaking a rule you assumed was fixed. That moment --- the shift from "these are the rules" to "these are the rules right now" --- is the emotional core of rule-breaking as a design tool.

Into the Breach (2018)
A tactics game with perfect information and strict constraints: a small grid, few units, and every enemy move visible before it happens. Into the Breach demonstrates how severe constraints produce the deepest choices. Every turn is a puzzle where you can see all the information, but the number of viable solutions is limited and every choice involves a genuine trade-off. Study the design of the grid size --- the game has eight squares by eight squares (the same as chess), and that constraint is essential to its depth.

Getting Over It with Bennett Foddy (2017)
A game built entirely around a single constraint: you can only move by swinging a hammer attached to your character's body. There is no checkpoint system. Falling means losing potentially hours of progress. The game is a meditation on rules, fairness, and the implicit contract between player and designer. Foddy narrates the experience in real time, discussing constraint, frustration, and the philosophy of difficulty. It is simultaneously a game and a design lecture.

Websites

Game Balance Concepts (gamebalanceconcepts.wordpress.com)
Ian Schreiber's free online course covers game balance, which is fundamentally about how rules interact and how those interactions produce (or fail to produce) fair and interesting play. The course is practical and includes exercises. Particularly relevant to this chapter are the entries on dominant strategies, intransitive relationships, and feedback loops.

Explorable Explanations (explorabl.es)
A collection of interactive articles that demonstrate how rules produce emergent behavior. Several entries visualize possibility spaces, feedback loops, and system dynamics in ways that static text cannot. Particularly recommended: Nicky Case's "The Evolution of Trust" (an interactive exploration of game theory that makes the relationship between rules and outcomes tangible) and "Parable of the Polygons" (a visualization of how simple individual rules produce complex collective patterns).
