Game Culture and Technology

• Games as immersive, experiential literary form --
  game play as emergent narrative
• Gaming as rapidly growing global industry
• Modding and making games as practice-based
  learning and career development
• Games as new media and cultural form
• Game culture as social movement

What is free/open source software development?

• Free (as in freedom) vs. open source
• Freedom to access, browse/view, study, modify and
  redistribute the source code
• Free is always open, but open is not always free
• F/OSSD is not software engineering
• Different F/OSSD can be faster, better, and
  cheaper than SE in some circumstances
• F/OSSD involves more software development tools,
  Web resources, and personal computing resources

16
OSS Development Models

• Free Software (GPL)
• Open Source (BSD/MIT, Mozilla, Apache)
• Corporate Source (Hewlett-Packard)
• Consortium/Alliance (OSDL, SugarCRM)
• Corporate-Sponsored (IBM-Eclipse, Sun-Netbeans,
  Sun-OpenOffice, HP-Gelato)
• Shared Source (Microsoft)
• Community Source (Sakai, Westwood)

17
OSSD Project Characteristics

• OSS Developers are always users of what they
  build, while OSS users (gt1) are also OSS
  developers
• Requires critical mass of contributors and OSS
  components connected through socio-technical
  interaction networks
• OSSD projects emerge/evolve via bricolage
• Unanticipated architectural (de)compositions
• Multi-project component integrations
• OSSD teams use 10-50 OSSD tools to support their
  development work

18
OSSD Project Characteristics

• Operational code early and often--actively
  improved and continuously adapted
• Post-facto software system requirements and
  design
• OSSD is not Software Engineering
• OSSD has its own -ilities which differ from
  those for SE
• Caution the vast majority of OSSD projects fail
  to grow or to produce a beta release.

19
F/OSS Processes for Requirements or Design

• F/OSS Requirements/Designs
• not explicit
• not formal
• F/OSS Requirements/Designs are embedded within
  informalisms
• Example OSS informalisms to follow (as screenshot
  displays)
• F/OSS Requirements/Design processes are different
  from their SE counterparts.

Evolutionary redevelopment, reinvention, and
redistribution

• One recurring evolutionary dynamic of F/OSSD is
  reinvention
• Reinvention enables continuous improvement
• F/OSS evolve through continuously emerging
  mutations (incremental innovation/adaptation)
• Expressed, recombined, redistributed via
  incremental releases

23
Evolutionary redevelopment, reinvention, and
redistribution

• F/OSS systems co-evolve with their development
  community
• Success of one depends on the success of the
  other
• Closed legacy systems may be revitalized via
  opening and redistribution of their source
• When enthusiastic user-developers want their
  cultural experience with such systems to be
  maintained.

24
Project management and career development

• F/OSSD projects self-organize as a meritocractic
  role-hierarchy and virtual project management
• Meritocracies embrace incremental innovations
  over radical innovations
• VPM requires people to act in leadership roles
  based on skill, availability, and belief in
  project community
• F/OSS developers want to learn about new stuff
  (tools, techniques, skills, etc.), have fun
  building software, exercise their technical
  skill, try out new kinds of systems to develop,
  and/or interconnect multiple F/OSSD projects
  (freedom of choice and expression).

Socio-technical and cultural evolution processes

• New processes under study
• Joining and contributing to a project in progress
• Role-task migration from project periphery to
  center
• Alliance formation and community development
• Independent and autonomous project communities
  can interlink via social networks that manipulate
  objects of interaction
• Enables possible exponential growth of
  interacting and interdependent community as
  socio-technical interaction network

28
Game related RD efforts

• one research problem for game software
  development
• visual and performing arts
• Games as cultural media
• science and technology education
• Games for informal education in science

29
(One) software development research problem for
games

• What is the best way to rapidly create
  networked games, game worlds, and play
  experience?
• best gt
• faster, better, cheaper
• open source (e.g., BSD/MIT style license)
• (global) community-based development,
  contribution and support
• Fun, enjoyable, intrinsically motivating,
  disruptive, etc.
• Modification, Construction, or Generation?

T.Rex

• Game story task 1 (grades 1-2)
• How does a T.Rex stand and run with short arms
  (front legs) and a long tail?
• How might the tail help the dinosaur when eating?
• Domain requirement must address national/CA
  science education standards
• Example learning task Place and (re)size tail
  and neck vertebra into see-saw balance system

41
T.Rex SEE-SAW BALANCE PUZZLE

• Demonstrates see-saw like T.Rex engineering
• Kids add tail segments to achieve correct balance
  for raptor skeleton

Computer Games in Libraries

• Libraries as community centers for games culture
  and technology
• New game opportunities for public libraries
• Science learning games
• Game-based graphic novels
• Game modding
• Library-specific games

46
Library-Specific Games

• Knowledge Quest
• navigational, adventure/discovery game
• find and assemble knowledge from library
  resources
• acquire practice and skill of library researcher
• resident librarians as game masters/mentors
• open source game engine, content development,
  and community participation

47
Summary observations

• We find F/OSSD is helping to drive computer game
  culture and technology
• We seek to break down barriers between art,
  science, technology, culture through computer
  games, game environments, and open source
  experiences
• We seek to create a new generation of informal
  learning tools and techniques, together
  with a global community of developers and users,
  through a massively shared, participatory
  collaborative learning environments.
