This has enabled players from different cultures to inhabit the same virtual game world, bypassing any geographical or cultural boundaries found in the real world. These 3D game worlds ask the player to use the basic principles of spatial awareness and movement from the real world, and are often virtual representations of real world environments. These spaces are designed for players from all nationalities to inhabit concurrently. There is now a need to determine design considerations for these multicultural multiplayer game worlds but any investigation must consider the historical evidence from the games industry of cultural differences in gameplay preferences. This thesis discusses the effect of cultural knowledge on the spatial design and interpretation of three-dimensional game environments that are based on real world affordances. A new methodology for the comparative analysis of the design of three- dimensional game environments is established using Space Syntax metrics. This facilitates the discussion of cultural models applied to design thinking for the implementation and interpretation of game environments. Through spatial metrics the analysis of the intelligibility underlying three-dimensional game environments is correlated to the imageability of the projected two-dimensional screen image. The application of this methodology to internationally popular, and culturally specific, game environments establishes new knowledge on tacit cultural influences within game design processes. The analysed intelligibility of the environments indicates cognitive differences between Eastern and Western cultures, already recognised in the interpretation of two-dimensional imagery, also exist within the design and interpretation of three-dimensional game spaces. This study establishes a new methodology through the analysis of intelligibility for design research into game environments. The resulting evaluation of tacit cultural influences within the design of the environments establishes new cultural differences and commonalities. These design characteristics can inform future game design methodologies within industry for the design and implementation of multicultural game environments. iii Acknowledgements This research question was originally formed during my Masters studies in Game Design in 2002. During my subsequent travels as a design educator I was constantly reminded that I had not found how cultural differences I encountered might determine differences in game worlds. I am thankful to my supervisory team for having the faith in me after our first meeting to consider that I might be able to resolve at least some element of this question. I would like to thank my Director of Studies Dr Gareth Bellaby who has offered guidance and support on this journey through a wide range of academic subject areas. I am grateful to all of my supervisory team. Professor Lik-Kwan Shark whose rigour developed my confidence to push methodologies into more mathematical areas that I would normally back away from. Professor Simon Robertshaw who saw the potential in the problem and offered encouragement throughout bringing different design viewpoints to bear on the study. Professor Chris Meigh-Andrews who led the discussion into digital arts and cultural practices that helped balanced the maths and keep me sane. Finally I would like to express my eternal love and gratitude to my wife who has offered me nothing but patience, support and understanding through the trials and tribulations of this study. iv Table Of Contents Chapter Page Chapter 1: Introduction .................................................................................... 1 1.1 Background 1 1.2 Structure of the Thesis 7 Chapter 2: A Design Research Methodology ............................................... 10 2.1 Design Research 12 2.2 Experiential Knowledge 14 2.2 Spatial Embodiment in the Game Space 18 2.3 Imageability and Intelligibility 20 2.3.1 Imageability 21 2.3.2 Intelligibility 23 2.3.3 A Method for Capturing the Qualities of an Environment 24 Chapter 3: Frameworks for Design?
