CSCE 590E Spring 2007

Understanding Fun

By Jijun Tang

Announcements l.jpg

  • We will meet in 1D11 on Wednesday, 4:00pm (again)

  • Each group should give me the names after class (paper or email)

  • Please start thinking games you want to design (do not worry about techniques at first)

Homework results l.jpg
Homework Results

  • Some people did not turn in the homework

  • Almost all turned in are good

  • The most played games are:

    • Super Mario Bros, Final Fantasy, The Legend of Zelda, Half-Life / Counterstrike, World of Warcraft, SimCity, X-Wing, Age of Empires, Diablo, Metal Gear Solid, Need for Speed, StarCraft, Tetris

Volunteers l.jpg

  • High school kids visiting

  • On Thursday morning and afternoon, 90 minutes each

    • 10:30-12:30

    • 1:00-3:00

  • We want to teach them flash games

  • We need experts in flash to help the instruction and supervision

What is fun l.jpg
What is Fun?

  • Game is all about fun

  • Dictionary: Enjoyment, a source of amusement

  • It is important to consider underlying reasons

  • Funativity – thinking about fun in terms of measurable cause and effect

Why fun l.jpg
Why fun?

  • It’s deep in our evolution root, and we must look to our ancestors (200 yrs of tech advancement haven’t changed our instinct)

  • Cats, dogs, etc play to learn basic survival skills (physical and social)

  • Games are organized play

  • Human entertainment is also at its heart about learning how to survive

  • Social rules are also critical to us

Surviving l.jpg

  • Life is all either work, rest, or fun

  • To survive, we must work

    • Our ancestors were those who survive

    • The survive skills are passed down

  • Who is more likely to survive?

Learning is fun l.jpg
Learning is fun

  • Fun is about practicing or learning new survival skills in a relatively safe setting

  • People who didn’t enjoy that practice were less likely to survive to become our ancestors

Hunting and gathering l.jpg
Hunting and Gathering

  • Basic skills are hunting and gathering

  • Current popular games reflect this

  • It’s a good start point to design games

  • Shooters, wargames = hunting

  • Powerups, resources = gathering

  • Sims, MMO = social, tribal interaction

Natural funativity theory l.jpg
Natural Funativity Theory

  • All funs are derived from practicing survival and social skills

    • Key skills relate to early human context

    • Often in modern guise: play chess, football, dance, etc

  • Three overlapping categories

    • Physical

    • Social

    • Mental

Physical fun l.jpg
Physical Fun

  • Sports

    • Enhance our strength, stamina, coordination skills

    • Winning is also a mental fun

  • Exploration

    • Knowledge of surrounding areas

    • Explore unknown

  • Hand/eye coordination and tool use are often parts of fun activities – crafts

  • Physical aspect to gathering “stuff”

Social fun l.jpg
Social Fun

  • Storytelling is a social activity

    • First virtual reality

    • Learn important lessons from others

  • Gossip, sharing info

  • Flirting

  • Showing off

Mental fun l.jpg
Mental Fun

  • Humans have large brains

  • Abstract reasoning practice

  • Pattern matching and generation

    • Music

    • Art

    • Puzzles

  • Gathering also has mental aspect, categorizing and identifying patterns

  • Gambling

Multipurpose fun l.jpg
Multipurpose Fun

  • Many fun activities have physical, social and mental aspects in combination

  • Games that mix these aspects tend to be very popular

  • Incorporate ways to practice these skills to increase the popularity of games

Great games l.jpg
Great Games

  • A great game is a series of interesting and meaningful choices made by the player in pursuit of a clear and compelling goal

    • Must have choices, or it is movie

    • Must be a series of choices or it is too simple to be a game

    • Must have a goal or it is a software toy (some goals may be implicit, like Sims)

    • With multiple player games players may bring their own goals

Qualities of choice l.jpg
Qualities of Choice

  • Terms in which to discuss choices

    • Hollow – lacking consequence

    • Obvious – leaves no choice to be made

    • Uninformed – arbitrary decision

    • Dramatic – strongly connects to feelings

    • Weighted – good and bad in every choice

    • Immediate – effects are immediate

    • Long-term – effects over extended period

    • Orthogonal – choices distinct from each other

Interesting and meaningful choices l.jpg
Interesting and Meaningful Choices

  • Choices may be dull and uninteresting because it was easy to code that way

  • Or it may be the reflection of a lazy designer

  • Meaningful choices are perceived by the player as having significant consequences

  • May not have actual consequences

Clear and compelling goal l.jpg
Clear and Compelling Goal

  • Clear goals

  • It is not fun to flounder aimlessly

  • Compelling goals are goals that follow the concepts in Natural Funativity

  • Survival is always a compelling goal

A series of choices l.jpg

No choice

A Series of Choices

A series of choices25 l.jpg
A Series of Choices

  • Meaningless choices

  • Obviously fold back into same path

  • Players discover this quickly

A series of choices26 l.jpg

Infinite choices

Quickly become unmanageable

A Series of Choices

A series of choices27 l.jpg

Choose wisely

Kill off player with any wrong choice

Better but frustrating (Dragon’s Lair)

A Series of Choices

Classic game structure l.jpg
Classic Game Structure

  • A convexity

  • Starts with a single choice, widens to many choices, returns to a single choice

Convexity qualities l.jpg
Convexity Qualities

  • Go from one to many to one

  • Can be a level, an act, an episode

  • Can be any kind of choice

    • Geography, weapons, tools, skills, technologies, quests

  • Examples

    • Exploring an island

    • Technology build tree

Fractal structure l.jpg
Fractal Structure

  • Large scale structure repeated on medium, smaller scales, like a coastline

  • In the case of convexities, each circle is not a single choice, but a convexity

  • Age of Empires example

    • Take a defensive stance, create squad to defend left flank, collect resources to build a legionnaire, etc.

A series of convexities l.jpg

Many games are chains of convexities

Points of limited choice (A) alternate with points of many choices (B)

A Series of Convexities

A series of convexities32 l.jpg
A Series of Convexities

  • Many overlapping convexities in great games

  • Examples include Halo, Zelda games, Civilization, Diablo II, many others

  • Player can be starting one task or area, in the middle of another, and at the end of a third, all simultaneously

Why is this good l.jpg
Why Is This Good?

  • Give the player choice but not an infinitely expanding set of choices

  • Mix of some “any order” choices (B) and some in fixed order (A), blending freedom with linear storytelling

  • Can be structured so players see most of the game, minimizing waste

  • Can have difficulty go up in new levels

Psychological advantages l.jpg
Psychological Advantages

  • Alternating intense learning with time to practice is the best way to master new skills

  • Gradual learning and introduction of new skills at the heart of fun game play

  • “Easy to learn, difficult to master”

  • Always let players practice

The concept of flow l.jpg
The Concept of Flow

  • Flow is a state of exhilaration, deep sense of enjoyment

  • Usually when a person’s body or mind is stretched to its limits to accomplish something difficult and worthwhile

  • Avoid frustration or boring

The flow channel l.jpg
The Flow Channel

  • Start with relatively low level of challenge to match starting skill levels

  • Gradually increase challenge

  • Fast enough to prevent boredom

  • Not so fast as to induce frustration

The flow channel38 l.jpg
The Flow Channel

  • Flow state is common while developing the Physical, Social, and Mental skills noted in Natural Funativity

  • Best to introduce skills one at a time, let player master them, move on to new

  • This results in staggered increase in difficulty (wavy difficulty line)

Typical game mechanisms l.jpg
Typical Game Mechanisms

  • High difficulty increase: Boss monsters, climactic battles, quest resolutions

  • Low difficulty increase: Bonus levels, new resource- and treasure-rich areas, series of easy “minion” enemies

  • Overlap introduction of new skills, areas to explore, tools, enemies

Story and character l.jpg
Story and Character

  • Back to “interesting choices” and “compelling goals”– how to achieve?

  • Story and character can add emotional association, strengthen reaction

  • Storytelling has long history, but interactive storytelling can differ critically from traditional linear modes

Interactive storytelling l.jpg
Interactive Storytelling

  • Blend storytelling with design early

  • Use experienced interactive writers

  • “Do, don’t show”– let players experience story through interaction

  • Make it personal by having players make key choices, events affect them

It s all about interactivity l.jpg
It’s All About Interactivity

  • Don’t make choices for the player

  • Story should add emotional context to the choices

  • Keep any cut scenes brutally short

  • Break up non-interactive sequences by adding interactivity, even if very simple

Characters l.jpg

  • Characters can make the game world seem more real and exciting

  • Bold stereotypes may seem crude but are better than colorless characters, and can help avoid boring exposition

  • Bring out character through action, not description or exposition

Gameplay trumps story l.jpg
Gameplay Trumps Story

  • If you have a conflict between gameplay or story, first look for a compromise that favors both

  • Failing that, make sure that the gameplay is good at expense of story

  • Always signal player clearly in narrative to interactive transitions with visuals, audio

What is good game ideas l.jpg
What is Good Game Ideas

  • Creative is the key

  • Start from our survival instincts

  • Play other games, search Internet

  • Examine current games and see what you can improve (AI, graphics, strategy, speed, multiple-player)

  • Mix ideas/plays from several games

  • Examine books, movies, comics, etc. (pay attention to license)

How to get good idea l.jpg
How to Get Good Idea

  • Brainstorming meetings with everyone attending and actively involved

  • Ensure free exchange of ideas, no idea is stupid idea now

  • Make goals clear, ignore technique problems first

  • Stay focused, list points must be achieved, with possibility of changes

  • Make sure everyone is heard, and take detailed notes, send notes to everyone after the meeting

Brainstorming l.jpg

  • You can start with game play

    • Decide player interactions and style

    • Determines engines/hardware

    • Limitations of total resources needed for game

  • You can start with story

    • In some genre (RPG) story is central

    • May determine how players and game play interact

    • Technology should match story line

    • Compromise

Brainstorming49 l.jpg

  • You can start with technology

    • Game engine characteristics (rendering, AI, language parsers, etc.) often dictates type of game that can be developed

    • It also determines user interaction possibilities

    • It is generally better to find a topic first and then select a genre rather than the reverse
