What’s All This About Then • Discussing game design! • Focusing on Mechanics, Dynamics, Aesthetics • Analysis of what fun is, why games have it, and   how to design for it • Pointing out where game design knowledge can be used for UX, UI, community, project, and company building

Slide 15

Slide 15 text

What We Won't Be Covering • Any programming whatsoever • Learning how to use a game engine • Learning how to get a job as a game designer

Slide 16

Slide 16 text

It’s about play

Slide 17

Slide 17 text

Why do we play games? Because they're fun!

Slide 18

Slide 18 text

Why do we play games? • But: • Why are they fun? • What do we mean when we say "fun"? • These are big, contentious questions with no single answer • Here's one answer:

Slide 19

Slide 19 text

Why are games fun? • Games elicit specific feelings in their players • Discovery • Power • Teamwork • Skilfulness • Fear • More... • We play games because we like experiencing these feelings • Similar reason to why we like movies, books, TV, theatre, art..

Slide 20

Slide 20 text

Why are games fun? How do games elicit these feelings?

Slide 21

Mechanics, Dynamics, Aesthetics LeBlanc, Hunicke & Zubek 2004

Slide 22

Slide 22 text

• Games are unpredictable (to varying degrees) • Player choice aﬀects what happens • The choices available to the player are created by the game designer How are games diﬀerent from other media?

Slide 23

Slide 23 text

What Choices Are Created? • Players interact with games in very specific, constrained ways

Slide 24

Slide 24 text

• Players take turns moving pieces • Pieces have diﬀerent rules for moving • Pieces capture other pieces • You win when you capture the king (more or less)

Slide 25

Slide 25 text

• One player is "it" • If the "it" player touches another player, that player becomes "it"

Slide 26

Slide 26 text

• Jump over the rope • If the rope hits you, it's the next person's turn • Arguably not a game?

Slide 31

Slide 31 text

Our Definition For our purposes, a game is: anything in which you play, subject to defined rules.

Slide 32

Slide 32 text

ANYWAY

Slide 33

Slide 33 text

• Walking, running • Weapons • Collectables • AI shoots at you • Hit points • Lots more..

Slide 34

Slide 34 text

• Resource collection • Buildings • Units • Fog of War • Orthogonal unit diﬀerentiation

Slide 35

Slide 35 text

Mechanics • We call these game rules "mechanics" o Why not just "rules"? o Rules are instructions. o Mechanics are descriptions of how systems function. • Players interact with these systems!

Slide 36

Slide 36 text

Dynamics • A thermostat has these mechanics: o "If the temperature is below 23°C, turn on the heater" o "If the temperature is above 23°C, turn on the air conditioner"

Slide 37

Slide 37 text

• This creates negative feedback - the system will work to try to settle on a single value Dynamics Heater On Heater On Cooler On Cooler On

Slide 38

Slide 38 text

Dynamics • Mechanics combine together to create dynamics. • “Tag” is a good, simple example. o Mechanic: The goal of the game is to not be "it". o Mechanic: When the player who is "it" touches you, you are "it". o Dynamic: the player who is "it" moves towards players who are not "it", who then flee. • Behaviour is separate from mechanics.

Slide 39

Slide 39 text

Dynamics • Another, mostly abstract example:  o Mechanic: Players can earn points, and can cause other players to lose points. o Mechanic: The winner is the first player with 10 points. o Dynamic: When a player gets close to winning, other players will gang up on them and bring them down.

Slide 40

Slide 40 text

Dynamics • Closely related to strategy, but not the same thing • If a game mechanics mean playing a certain way will win the game more often, the fact that you end up playing that way is the dynamic

Slide 41

Slide 41 text

Dynamics • Often diﬃcult to work out from just reading the rules • The complexities of a game come from interacting rules

Slide 45

Slide 45 text

Aesthetics • Dynamics have eﬀects on players. • In tag, the "it" player chases you o This makes you feel hunted • When you're "it", you chase the other players o This makes you feel like a hunter

Slide 46

Slide 46 text

Aesthetics Sensation Game as sense-pleasure Fantasy Game as make-believe Narrative Game as unfolding story Challenge Game as obstacle course  Fellowship Game as social framework Discovery Game as uncharted territory Expression Game as soap box Submission Game as mindless pastime Aesthetics are the way that games make us feel. From 8kindsoﬀun.com

Slide 47

Slide 47 text

Aesthetics • Arguably, aesthetics are what we're usually talking about when we describe "fun". • They're often what players are subconsciously looking for when selecting a game o "I want a game that makes me feel powerful" o "I want a game that makes me feel like I'm working in a team" o "I want a game where I can have fun with my friends"

Examining a game using MDA

Slide 51

Slide 51 text

“The Resistance” • Rebels vs Evil Government • Most players are “rebels” (good guys) • Some players are “spies” (bad guys) • Spies know who their fellow spies are, but rebels don’t know

Slide 52

Slide 52 text

“The Resistance” Rules 1. Current leader picks a team to go on a mission 2. All players publicly vote on whether this team should go or not 3. Team members secretly vote whether the mission should succeed or not 3 succeeds = rebels win 4. Next player becomes the leader 3 fails = spies win

Slide 53

Slide 53 text

“The Resistance” Mechanics • At a higher level: • Hidden information • Fixed game time • Perfect knowledge of own state • Subset of players have perfect knowledge of full state

Slide 54

Slide 54 text

“The Resistance” Dynamics • Accusation • Rebels end up looking for evidence of spies • Deduction • Rebels need to work out who they can trust; this leads to: • Creation of “circles of trust” • Small exclusionary groups form, often hostile to actual non-spies • Camouflage • Spies can choose to help missions succeed • Misdirection • “I’m not the spy! You’re the spy!” • Sacrifice • One spy denounces another, to gain trust

Slide 55

Slide 55 text

“The Resistance” Aesthetics • For rebels: • Paranoia • Uncertainty • For spies: • Silent teamwork • Fear of discovery

Small rule changes mean big gameplay changes

Slide 58

Slide 58 text

Two new rules

Slide 59

Slide 59 text

Two new rules • Same as "The Resistance", but with an Arthurian theme • One Good player is Merlin • Knows who all the Evil players are • One Evil player is the Assassin • At end of game, if Good has won but the Assassin can correctly identify Merlin, Evil wins

Slide 60

Slide 60 text

New Dynamics • Merlin tries to give information to good players, without giving themselves away • Players (both Good and Evil) try to discover Merlin's identity • Evil players pretend to be Merlin • Merlin tries to find independent justifications for stuﬀ they know • Multiple routes to victory for Evil players • Merlin discovery gambits • Merlin discovery counter- gambits • Merlin discovery counter- counter-gambits

Slide 61

Slide 61 text

New Aesthetics • Frustration (for Merlin) • Out-thinking • Fast talking • Guardianship (for Good players) • Vigilance (for Assassin and for Good players)

Slide 62

Slide 62 text

Dynamics create aesthetics through narrative

Slide 63

Slide 63 text

Games tell stories Not just written narrative, but emergent narrative

Reinforcement through setting

Slide 68

Slide 68 text

Pre-Written Narrative (Artist’s Impression) Marc Laidlaw

Slide 69

Slide 69 text

Reinforcement through dynamics • Player is deliberately starved of ammo • Earlier areas featured plenty of ammo • Sudden shift in availability creates contrast and unease (“Why can’t I find ammo? Am I not playing this game right?") • To compensate, player is forced to improvise and get closer than usual to dangerous enemies • New mechanics designed to reinforce scariness

Slide 70

Slide 70 text

• Small • Fast • Jump at player • On hit, player’s health drops to 1%

Slide 71

Slide 71 text

Eﬀective Dynamics • Games tell stories through gameplay. • This is in addition to any prewritten narrative. • Games are important because they’re the only medium for interaction in which the narrative depends entirely on the player.

Effective Dynamics • Effective written stories have dramatic tension. • Effective emergent stories have dramatic tension, too!  • But what is dramatic tension?

Slide 75

Slide 75 text

Dramatic Tension Time Rising tension Climax Resolution/ Denouement

Slide 76

Slide 76 text

Dramatic Tension Time Meet Luke, sand people, escape Tatooine, escape Death Star Attack Death Star Yay, medals

Slide 77

Slide 77 text

Dramatic tension • How does dramatic tension form? • Through a combination of: • Uncertainty • Inevitability

Slide 78

Slide 78 text

Uncertainty The outcome is unknown. Anyone could win or lose.

Slide 79

Slide 79 text

Inevitability The contest between players is moving forward towards resolution, and the outcome is imminent.

Slide 80

Slide 80 text

Tension requires both of these • Without uncertainty, the outcome is too obvious • Without inevitability, the outcome is too distant

Losing Players Can Make A Comeback Uncertainty Fixed Duration of Race Inevitability The first person to pass the finish line wins the game. When players collide with item boxes, they receive a random item. One item is the Blue Shell, which is a homing missile that slows down players in front of you. When a player is in last place, they have an increased chance of collecting blue shells. ` Holy crap! That was so close, but you hit me with a shell just before I crossed the finish line! I hate you! Let’s go again!

No knowledge of what’s behind each door Uncertainty Number of rooms is finite Inevitability The player can walk from room to room. Rooms contain items, like books, boxes, documents, keys… Items can be picked up and examined. ` Oh man, I hope things work out for her in the end…

Game design for not-games

Slide 100

Slide 100 text

This is not gamification

Slide 101

Slide 101 text

User stories • "As a , I want so that ” • Action -> Desirable outcome • What -> Why • Mechanic -> Aesthetic • Consider thinking about how the action leads to the desirable outcome through the expression of your UI’s mechanics

Slide 103 text

Analysing “desire paths” in software • Mechanic: Walking is easier along paths. • Mechanic: When people walk on terrain, a rough path is gradually formed. • Dynamic: People create new paths that are shorter than the formal, paved paths. • “Aesthetic”: People are unhappy at ugly paths.

Slide 104

Slide 104 text

Analysing “desire paths” in software Understand how people are interacting with your existing mechanics, and identify if they’re resulting in an aesthetic that you don’t want. If they are, change it.

Slide 105

Slide 105 text

Analysing “desire paths” in software • Mechanic: The text of tweets can be copied and pasted. • Mechanic: Tweets have a limited length. • Dynamic: To indicate the source of a copied tweet, users add attribution (“RT @username: text of original tweet”) • Aesthetic: Dissatisfaction - users have to reword tweets • New mechanic: Define a new type of tweet, called a “retweet”, that embeds the original tweet

Slide 106

Slide 106 text

Addendum: People make contests out of anything • Mechanic: The number of retweets is counted • Mechanic: The number of users who favourite a tweet is also counted • Dynamic: Retweets expose a tweet to more users, favourites do not • Dynamic: Users craft their tweets to be retweeted more often • Aesthetic: Retweets are considered more valuable • Aesthetic: Weird Twitter

Mechanics don’t directly lead to outcomes • They rely on the expression of the rules through dynamics • This is why “mandatory fun” rules never result in actual fun • You can’t design fun, but you can design for fun • You can’t design a positive company culture, but you can design systems and mechanisms that reinforce positive elements of a culture
