Testing Rules

Req 4c — Observe New Reactions

4c.
Play the game with one rule or objective change, observing how the players’ actions and emotional experiences are affected by the rule change. Repeat this process with two other changes.

Now you test your ideas in the real world. This is not about whether your changes are “good” or “bad.” It is about what actually happened when players met the new rules.

A rule change can affect three things at once: what players do, what they feel, and what kind of game experience the session becomes. Your job is to notice those shifts clearly.

Observe, Don’t Just Participate

If possible, spend part of the session watching instead of playing full-out. Designers often learn the most by noticing hesitation, confusion, excitement, and repeated behavior patterns.

Look for signs like these:

Repeat the Process Three Times

Three-column comparison of the same game under different rule changes, showing different player behavior such as teamwork, rushed play, and confusion.

The requirement asks you to repeat the process with three different changes. That means you need separate notes for each test. Treat them like three mini-experiments, not one giant blur.

A simple format works well:

Change testedWhat players didHow they seemed to feelSurprise result
New scoring ruleTook more risksMore excited, less patientRounds ended faster

You do not need to guess private thoughts, but you can observe visible reactions: cheering, slowing down, arguing, asking questions, or getting quiet.

What to watch during each test

Focus on evidence, not just opinions
  • Actions: Did player decisions change?
  • Pace: Did the game speed up or slow down?
  • Clarity: Did the change make the rules easier or harder to understand?
  • Balance: Did one strategy or player gain too much advantage?
  • Emotion: Did players seem more engaged, more stressed, more bored, or more confident?

Player Emotion Is Part of the System

Designers sometimes focus only on mechanics, but emotional experience matters just as much. A rule that creates suspense can be exciting. A rule that creates confusion can feel unfair. A rule that gives struggling players a chance to recover may feel encouraging.

That is why the requirement specifically mentions emotional experiences. The goal of game design is not just to move pieces around. It is to create an experience people remember.

Expect Surprises

Even smart predictions can be wrong. Players are inventive. They may exploit loopholes, ignore the intended strategy, or turn your “fair improvement” into a confusing mess. That is normal. In fact, it is valuable.

Surprises are where design learning happens. If players keep finding a shortcut you did not expect, that may reveal a balance problem. If they smile more under one change even though the score stays close, that may reveal a better emotional tone.

Keep Your Notes Usable

Later, in Req 4d, you will explain how accurate your predictions were. That is hard to do if your notes are vague. Write down specifics like “players stopped passing and took more direct shots” or “the new objective made teammates talk constantly.”

Those details are more convincing than “it was fun.”
