  1. Game Design: Interactivity(4190.420Computer Game) Jehee Lee Seoul National University

  2. Interactivity • Interactivity is the most important factor of games • “Fun factor” might be equally important, but difficult to formalize • Computers gave gaming a big boost • The real power of computers lies in its interactivity

  3. What is interactivity • The essence of interactivity can be observed in conversation • Listen • Think • Speak back • A cyclic process in which two active agents alternately (and metaphorically) listen, think, and speak.

  4. How Do We Measure Interactivity ? • Good experience with conversation requires • Listen well • A conversation with people who do not listen to what you are saying • Think well • A conversation with people who listen well, but cannot understand the context • Speak well • A conversation with people who listen and think well, but cannot express themselves

  5. Interactivity in Games • How much of what the player might desire to say/do does the game permit the player to actually say/do ? • How well does the game think/process about the player’s inputs ? • How well does the game express its reactions ?

  6. Styles of Conversation • Rugby style • There is no turns. Everybody speaks simultaneously • Basketball style • There is a token; One person speaks at a time • The token is passed or intercepted frequently • Baseball style • There is a token; One person speaks at a time • The token is turning around and rarely intercepted.

  7. Degrees of Interactivity • Speed • Is fast turnaround better than slow turnaround ? • Eg) Shooting games versus Board games • Eg) VisiCalc versus Mainframe spreadsheet • Eg) BASIC versus compliers • Depth • The overall quality of an interaction depends on its depth as well as its speed • “Deeper” means “Penetrating closer to what makes you human” • Hand-eye coordinate, puzzle-solving, spatial reasoning, social reasoning

  8. Degrees of Interactivity • Choice • Interactivity depends on the choices available to the user • The “richness” of choices • Functional significance of each choice • Some games offer the player the opportunity to wander all over a huge region—but nothing interesting happens in the huge region • Perceived completeness • The number of choices in relation to the number of possibilities the user can imagine

  9. Low-Interactivity Games • Little Computer People • A small family moving around their dollhouse in the course of their daily activities • The player watch them • The sims is similar, but offers more interactivity • VCR games • Myst, The 7th guest • It is like watching movie occasionally pushing buttons to make decisions • Good visual and sound, but weak game play

  10. Low-Interactivity Games • Games for young children are usually less interactive • Low-interactivity games usually requires less decision-makings and workload than high-interactivity games • The player’s workload is not proportional to the quantity of decision-making • The workload of learning the rules is substantial • Eg) minimal-interactivity murder mystery game

  11. Creativity • The industry have reached a peak of creativity in game design during 80s and 90s • Nowadays, game design is a coldly mechanical process requiring little in the way of creativity

  12. Tightly defined genres • First-person shooter • The player blast bad guts as he navigates a complex 3D environment • He collects weapons and ammunition, sometimes solve puzzles • Platform games • Space Panic in 1981, Apple Panic, Donkey Kong • A series of “Mario” games are still selling and successful

  13. Tightly defined genres • Role-playing games • Dungeons & Dragons in the mid-1970’s • Moria, Wizardry, Ultima I, II, III, IV, V, VI, VII, so on • Only small changes have been made for the decades

  14. Where Does Creativity Come From? • How can “ordinary” people be creative ? • We don’t want to talk about a few geniuses • One idea is just as good as another (?) • Creativity is serious business • You don’t attain high levels of creativity by random daydreaming

  15. Association and Analogy • Our minds are associative • Many concepts in our minds are associated like a web • New ideas are generated by combining old ideas in novel ways • This combining process is not a simple additive one • New ideas are often attained by observing analogical patterns in the web of associations

  16. How to “Get Creative” • Reading • Stuff your head full of concepts and all their associations • More concepts and associations yield better possibilities • Wondering • An exercise in tightening up the web of associations

  17. Brainstorm • What is a brainstorm ? • Drive the problem deep into your subconscious • Spend days and nights • The solution will leap out at you • Great geniuses described their brainstorm experiences • A phase of intense emotional involvement • A quiescent period • The entire solution leaps upon them with suddenness
