About pattern collections n The large collection q q q n ~300 patterns Threshold to use Want to check potentially new patterns against this Reasons to identify new patterns The large collection is not complete q Need specialized patterns for projects q Make own small in-house collection q

Genesis of a Pattern – a model n n n Recognize Analyze Describe Test Evaluate (go back to Analyze) Outcome: q Clear definition of the pattern

Recognize n n n Patterns easy to recognize, difficult to define Play games, think games, dream games, design games, read about games Other areas for inspiration: software engineering, computer science, HCI, architecture, drama, myths and legends, psychology, philosophy of mind, choreography, music, visual arts, sociology, human relationships, economics, politics etc.

Recognize (where to look in games)

Analyze n n Analyze the group together but start with the main candidate The pattern in existing games: q q n Think about different genres (RTS, FPS, MMORPG, strategy, arcade games etc. ) Think about different kinds of games (board and card games, children games, table-top and live action RPGs Try to imagine the games without the pattern

Analyze n List games that do not have the pattern: q n Compare the games from each list q n n Try to find games in same genres as in the previous list What is the difference in game play? How the other ideas are related to the pattern? Are they part of it or separate? Relations to other patterns

Describe n n Draft out the first kernel definition (a couple of sentences) Draw a diagram: optional Describe how the pattern is used in the example games Relationships to existing patterns: q q q What other patterns are frequent in the example games? How the other patterns affect the pattern? Relations to other patterns

Describe n n What are the consequences of using the pattern? Are the other ideas part of this pattern? q n Or are they separate patterns? Modify and elaborate the description according to the template q q q Name Description Using the pattern Consequences Relations to other patterns

Test n Interaction design exercise: q q q n n Nothing else but the pattern (well, requires some extras) Why it is not a game? Add patterns or interactions to make it a protogame “Redesign” existing games to use the pattern Apply the pattern in your current work, if possible

Evaluate n n n Is this a pattern? Is it useful? Should it be part of another pattern? Should it be discarded altogether? Is the description sufficient? Start the Analyze-Describe-Test cycle again if need be

The Reality n n n The reality is messy… Abstraction of the process Analyze-Define-Test normally intertwined Pattern elimination, mutation, fusion, spinoffs possible in all phases Difficult work (at least for us) Some phases are better done in small groups

An example of identifying patterns n n n Board game Carcassonne (Klaus-Jürgen Wrede, published by Hans im Glück 2000) Simple Several interacting patterns

Example of pattern emerging from token use Tile-laying

Example of pattern emerging from closure use Enclosure

Example of pattern emerging from interaction Hovering Closure

Example of pattern emerging from experience Tension
