  6. We are Australian If we don’t make sense, let us

    know!

  8. None
  9. What We'll Be Doing • Game design! • Focusing on

    Mechanics, Dynamics, Aesthetics • Analysis of what fun is, why games have it, and how to design for it
  10. 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
  11. It’s about play

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

  13. 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:
  14. 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..
  15. Why are games fun? How do games elicit these feelings?

  16. Mechanics, Dynamics, Aesthetics LeBlanc, Hunicke & Zubek 2004

  17. • 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?
  18. What Choices Are Created? • Players interact with games in

    very specific, constrained ways
  19. •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)
  20. •One player is "it" •If the "it" player touches another

    player, that player becomes "it"
  21. •Jump over the rope •If the rope hits you, it's

    the next person's turn •Arguably not a game?
  22. Aside: Game Definitions game /gām/ n. (pl. -games) a non

    productive activity that involves a competition confined by procedures.
  23. Aside: Game Definitions game /gām/ n. (pl. -games) a non

    productive activity that involves a competition confined by procedures.
  24. Aside: Game Definitions game /gām/ n. (pl. -games) a formalized

    experience in which players make choices to have a meaningful experience. game /gām/ n. (pl. -games) an artwork characterized by an act of exploration. game /gām/ n. (pl. -games) an interactive object in which players interact with each other resulting in an unequal outcome. game /gām/ n. (pl. -games) a challenge in which players interact with each other resulting in a specific state of affairs. game /gām/ n. (pl. -games) a medium that involves a playful relationship representing a subset of the world. game /gām/ n. (pl. -games) a non productive activity that involves a competition confined by procedures.
  25. Aside: Game Definitions gamedefinitions.com

  26. Our Definition For our purposes, a game is: anything in

    which you play, subject to
  27. ANYWAY

  28. •Jump over the rope •If the rope hits you, it's

    the next person's turn •Arguably not a game?
  29. •Walking, running •Weapons •Collectables •AI shoots at you

  30. •Resource collection •Buildings •Units •Fog of War •Orthogonal unit

  31. 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!
  32. Dynamics • A thermostat has these mechanics: o "If the

    temperature is below 72°F, turn on the heater" o "If the temperature is above 72°F, turn on the air conditioner"
  33. • This creates negative feedback - the system will work

    to try to settle on a single value Heater On Heater On Cooler On Cooler On Dynamics
  34. 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.
  35. 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.
  36. 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
  37. Dynamics •Often difficult to work out from just reading the

    rules •The concept of discovered check is not obvious in the rules of chess
  38. 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
  39. 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 Aesthetics are the way that games make us feel. From 8kindsoffun.com
  40. 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"
  41. MDA Summary Mechanics Dynamics Aesthetics • Designers create mechanics •

    Mechanics, when played, create dynamics • Dynamics have aesthetic effects on players
  42. Players See This Differently Developer Player Mechanics Dynamics Aesthetics

  43. Examining a game using MDA

  44. “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
  45. “The Resistance” Rules •Each turn: •Current “leader” player picks some

    players to go on a “mission” •Players vote on whether this selection is good •Selected players secretly pick a “success” or “failure” card; these are gathered and shuffled, then revealed to everyone •If any “failure” cards were picked, the mission fails •Next player clockwise becomes leader •3 mission fails = spies win •3 mission successes = rebels win
  46. “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
  47. “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
  48. “The Resistance” Aesthetics •For rebels: •Paranoia •Uncertainty •For spies: •Silent

    teamwork •Fear of discovery
  49. Small rule changes mean big gameplay changes

  50. Two new rules

  51. 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
  52. New Dynamics •Merlin tries to subtly signal to known good

    players •Players (Good and Evil) try to discover Merlin's identity •Evil players pretend to be Merlin •Merlin tries to find independent justifications •Multiple routes to victory for Evil players •Merlin discovery gambits •Counter-gambits •Counter-counter-gambits
  53. New Aesthetics •Frustration (for Merlin) •Out-thinking •Guardianship •Vigilance (for Assassin)

  54. Dynamics create aesthetics through narrative

  55. Games tell stories Not just written narrative, but emergent narrative

  56. None
  57. Ravenholm is a scary level •Why? •Several well-placed elements combine

    to create a scary experience
  58. Reinforcement through dialogue •“That's the old passage to Ravenholm. We

    don't go there anymore." •Initial setup; establishes mystery ! •"Whatever you do, don’t go through Ravenholm!" •Clumsy line, but establishes Ravenholm as dangerous and reinforces mystery
  59. Reinforcement through setting

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

  61. 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
  62. • Small • Fast • Jump at player • On

    hit, player’s health drops to 1%
  63. 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.
  64. None
  65. None
  66. Effective Dynamics •Effective written stories have dramatic tension. •Effective emergent

    stories have dramatic tension, too!
 •But what is dramatic tension?
  67. Dramatic Tension Time Rising tension Climax Resolution/ Denouement

  68. Dramatic Tension Time Meet Luke, sand people, escape Tatooine, escape

    Death Star Attack Death Star Yay, medals
  69. Dramatic tension •How does dramatic tension form? •Through a combination

    of: •Uncertainty •Inevitability
  70. Uncertainty The outcome is unknown. Anyone could win or lose.

  71. Inevitability The contest between players is moving forward towards resolution,

    and the outcome is imminent.
  72. Tension requires both of these •Without uncertainty, the outcome is

    too obvious •Without inevitability, the outcome is too distant
  73. Dramatic Tension •Game dynamics can create both uncertainty and inevitability

  74. Sources of Inevitability

  75. None
  76. Sources of Uncertainty

  77. Sources of Uncertainty

  78. None
  79. Mechanics Dynamics Aesthetics

  80. 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!
  81. None
  82. None
  83. None
  84. 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…
  85. None
  86. None
  87. Dynamics are hard to intuit

  88. None
  89. Your goal is to fail as quickly as possible

  90. • Spend as little time as possible thinking about changes,

    and as much time as possible testing changes • Games are about interacting components • The only way to work out the next steps in your design is to put it in motion Fail Fast
  91. Fail Fast • Your first attempts will be terrible. •

    This is good. • Discover what you don't like about your work, make a change, and test it again. Repeat.
