Due to the high cost of manual content creation within the game development industry, methods for procedural generation of content such as game maps and levels have emerged. However, methods for generating game maps have remained relatively unexplored in competitive multiplayer contexts. Presumably, this is due to the opposing goals of generating game maps that are both interesting and fair. This study aims to explore the possibility of satisfying both these goals simultaneously by separating the generative phase from the phase that enforces fairness. In this endeavor, simple game maps for a generic multiplayer grand strategy game are generated using noise-based methods. The task of partitioning the game map fairly between the players is then modeled as a constrained categorical multiobjective minimization problem that is subsequently solved by two genetic algorithms, the reference-point-based algorithm NSGA-III and the decomposition-based algorithm MOEA/D-IEpsilon. In a primary study, the proposed partitioning method is evaluated based on the quality of the solutions produced, its scalability, and its ability to find symmetrical partitions of symmetrical game maps. The results show that the proposed method makes significant improvement from the initial guess but fails to produce completely fair partitions in general. Explanations and possible solutions to this are presented. The timing results indicate that the proposed method is not applicable in real-time contexts. However, the proposed method might still be applicable in online contexts if smaller game maps are considered and in offline contexts if larger game maps are considered. Finally, the partitioning results show that the proposed method successfully finds fair partitions of symmetrical game maps but fails to find the obvious symmetrical partitions. In a secondary study, the two genetic algorithms are compared to determine which algorithm produces dominating solutions and which algorithm produces most diverse solution. The results indicate that, for the partitioning problems considered in this study, the reference-point-based algorithm is both dominant and produces the most diverse solutions.

Digitala spel har blivit ett allt vanligare sätt för underhållning, där industrin har sett en stor ökning av användare, vilket har stor sannolikhet att fortsätta även i framtiden. Dessa spel har ökat i komplexitet i takt med den teknologiska utvecklingen från 90-talet tills idag, där Internet har haft stor påverkan och introducerat nya möjligheter. En utav dessa möjligheter är insamlingen av olika datatyper med olika syften och olika användningsområden inom ett spelutvecklingsföretag. Industrin har lockat mycket forskning angående processer och metoder som berör skapandet av dessa komplexa produkter, där förarbetet och själva skapandet av digitala spel tar upp majoriteten av forskning i jämförelse med vidareutvecklingen av dessa digitala spel efter lansering. Syftet med denna rapport är därmed att bidra med kunskap till det mindre utforskade området kring utvecklingsprocessen efter lansering av online multiplayerspel, samt undersökning och insamling av data och dess integrering i vidareutvecklingsprocessen. Första viktiga delen av rapporten är ett teoriavsnitt, skapad genom en litteraturstudie där denna bestod av att identifiera och hitta vetenskapliga artiklar med kunskap kring ämnet, där dessa var viktiga för att skapa en teoretisk grund för denna studie. Detta gjordes huvudsakligen genom vetenskapliga databaser och söktjänster, med hjälp av nyckelord relaterade till viktiga teorier. Den andra viktiga delen är empiriska studier i form av semistrukturerade intervjuer utifrån en intervjuguide med respondenter från olika spelutvecklingsföretag. Företagen som respondenterna jobbade för var Ghost Ship Games, Jagex, samt Bohemia Interactive. Dessa intervjuer har sedan analyserats och viktiga teman har identifierats utifrån respondenternas svar. Respondenterna har nämnt olika datatyper som kan täcka olika delar av företaget, men när det gäller vidareutveckling av spel har tre typer nämnts att ha störst påverkan. Dessa typer var datapunkter över hur spelet används av individer, kvalitetsdata av spelets prestanda samt feedback från användare. Metoderna för att samla in de förenämnda datatyperna består framförallt av enkäter som alla respondenter har nämnt att respektive företag använder för att samla in feedback, rapportering av bugs eller förslag på förbättringsområden. Utöver detta samlas även mer övergripande information genom digitala verktyg eller spelklienten för respektive spel. Där dessa verktyg är skapade inom företaget eller hanteras genom ett separat företag. Ghost Ship Games har nämnt en egen idealbild över hur spelet ska vara balanserat som företaget strävar efter, vilket tas i åtanke vid beslut som tas av utvecklarna som täcker respektive problem. Inom Jagex är det hela team som bestämmer tillsammans angående förändringar eller tillägg i spelet. En intressant aspekt var att för Jagex så är användarna en del av beslutsfattandet genom opinionsundersökningar. Beslutsfattandet inom Bohemia Interactive nämndes att ske huvudsakligen genom avdelningen för kvalitetssäkring, där dessa filtrerar insamlad information och sedan delegerar identifierade problem till rätt utvecklare inom företaget. Vidareutvecklingen inom företagen gjordes framförallt genom balansering med hjälp av spelmotorn för respektive spel. Ghost Ship Games fokuserar även på vidareutveckling av befintliga funktioner, system och verktyg, genom att omarbeta några av föregående delar. Inom Bohemia Interactive angående Arma 3 användes till exempel hotfixes eller helt nytt spelinnehåll genom DLC, liknande sker även inom Jagex i form av hotpatches. Övergripande så är vidareutvecklingsprocessen lik mellan företagen, genom de olika steg som har identifierats i denna rapport. Dessa kan beskrivas som en iterativ process där företag identifierar problem eller förslag för vidareutveckling, samlar in eller undersöker befintlig data för att bekräfta problem eller stödja förslag, implementerar lösning eller förslag, samt samlar in feedback och agerar utifrån feedback. / Digital games have become an increasingly common means of entertainment where the industry has seen a huge increase in users, something that is likely to continue in the future. These games have increased in complexity in line with technological developments from the 1990s to the present day, where the Internet has had a major impact and introduced new possibilities. One of these opportunities is the collection of different types of data with different purposes and different uses within a game development company. The industry has thus attracted a lot of research regarding processes and methods involved in the creation of these complex products, where the pre-processing and actual creation of digital games is in the vast majority of studies compared to the further development of these digital games after launch. The aim of this paper is therefore to contribute knowledge to the less explored area of the post-launch development process of online multiplayer games, as well as the investigation of data collection and its integration into the further development process. The first important part of the report is a theory section, created through literature review where this consisted of identifying and finding scientific articles with knowledge on the topic, where these were important to create a theoretical basis for this study. This was mainly done through scientific databases and search services, using keywords related to important theories. The second important part is empirical studies in the form of semi-structured interviews based on an interview guide with respondents from different game development companies. The companies the respondents worked for were Ghost Ship Games, Jagex, and Bohemia Interactive. These interviews were then analysed and important themes were identified based on the respondents’ answers. Respondents mentioned different types of data that could cover different parts of the company, but when it comes to further game development, three types were mentioned to have the most impact. These types were data points on how the game is used by individuals, quality data of the game's performance, and feedback from users. The methods for collecting the aforementioned data types consist mainly of surveys, which all respondents mentioned that the respective companies use to collect feedback, report bugs or suggest areas for improvement. In addition, more general information is also collected through digital tools or the game client for the respective game. Where these tools are created within the company or managed by a separate company. Ghost Ship Games has an ideal image of how the game should be balanced that the company strives for, which is taken into account when decisions are made by the developers themselves that cover the respective issues. Within Jagex, the whole team decides together on changes or additions to the game. An interesting aspect is that within Jagex, users are a part of the decision making process through opinion polls. Decision-making within Bohemia Interactive is mainly done through the Quality Assurance department, where they filter collected information and then delegate identified problems to the appropriate developers within the company. Further development within the companies is mainly done through balancing using the game engine for each game. Ghost Ship Games may also focus on further development of existing features, systems and tools, by reworking some of the previously mentioned elements. In Bohemia Interactive regarding Arma 3, are hotfixes or completely new game content through DLC used for example. Similar is also done in Jagex in the form of hotpatches. Overall, the further development process is similar between the companies, through the different steps identified in this report. These can be described as an iterative process in which companies identify problems or proposals for further development, collect data or investigate existing data, implement the solution or proposal, collect feedback and act on the feedback.
