Game companies are always looking for more ways to increase consumers and their revenue as well as how consumers purchase games. Several business models have been introduced that this thesis will look at, free-to-play, adding downloadable content to existing games, freemium and premium games. This thesis attempts to provide answers to what business models there are available for game developers and how that would influence the development of the single-player games to lower the point of entry for the consumers.  It will focus on narrative single-player games and will use the business models to try and answer the question. A survey was handed out that investigated the respondent’s reaction to changes for BioShock Infinite developer by Irrational Games. The models were presented and compared to how the respondents reacted to the questions. Together with how companies are releasing games now this thesis came to the conclusion that in order to lower the entry point, the games need to be split and released episodically, together with increased downloadable content that added further playability to the game.

I denna studie undersöks hur de grafiska aspekterna av karaktärsskapande påverkar spelare och deras engagemang i singleplayerspel. Syftet med studien är att undersöka vilken betydelse utseendet på spelarskapade karaktärer har för spelares engagemang och ifall det påverkar deras spelande. Semi-strukturerade intervjuer utfördes med sex deltagare där teman som bl.a. inspiration, motivation, form vs funktion och rollspelande uppkom. Slutsatsen var att det visuella utseendet har stor betydelse för spelare och bidrar till deras engagemang i spelet. Studien kan hjälpa spelutvecklare med att skapa spel med character creation som är uppskattade av spelare och ger dem en meningsfull upplevelse. / This study examines how the graphical aspects of character creation affects players and their involvement in single-player games. The purpose of the study is to investigate what significance the appearance of player created characters has to player commitment and whether it affects their gaming. Semi-structured interviews were conducted with six participants where themes such as inspiration, motivation, form vs function and role playing arose. The conclusion was that the appearance of the player created character had a big significance for players and that it contributed to player involvement in the game. The study can help game developers create games with character creation which are appreciated by players and give them a meaningful experience.

Cloud computing is a way to deliver high-performance services to clients who would not usually be able to handle the computations on their own. They rely on computers in the cloud performing the calculations and therefore ease the load on the client-side. The goal of this thesis is to find what factors affect the players' experience and how they affect the player. To handle this, we have done a user-based study on cloud gaming. The users get to play a fast-paced single-player game and a fast-paced multiplayer game against each other, while we collect data about their experiences. During the tests, we manipulated the players' network conditions, and afterward, they answered questions regarding their quality of experience. From the data collected, we can see that the frame age is the most important measurement for determining the players' in-game performance as well as the quality of experience. We are also able to see that from the quality of service measurements manipulated, the latency is the one affecting the player the most. Results from the multiplayer test would indicate that we can equalize the skill difference between the players without affecting the players quality of experience too much. These results are based on the advantage in ping time as well as frame age. From a developers perspective, this thesis emphasized the need to take frame age into account, and to try to manipulate the different parts of the frame age. The goal would be to ultimately lower the frame age and make the gaming experience more enjoyable for the player.

Digital games incorporate systems that allow players to customise and develop their controllable in-game representative (avatar) over the course of a game. Avatar customisation systems represent a point at which the goals and values of players interface with the intentions of the game developer forming a dynamic and complex relationship between system and user. With the proliferation of customisable avatars through digital games and the ongoing monetisation of customisation options through digital content delivery platforms it is important to understand the relationship between player and avatar in order to provide a better user experience and to develop an understanding of the cultural impact of the avatar. Previous research on avatar customisation has focused on the users of virtual worlds and massively multiplayer games, leaving single-player avatar experiences. These past studies have also typically focused on one particular aspect of avatar customisation and those that have looked at all factors involved in avatar customisation have done so with a very small sample. This research has aimed to address this gap in the literature by focusing primarily on avatar customisation features in single-player games, aiming to investigate the relationship between player and customisation systems from the perspective of the players of digital games. To fulfill the research aims and objectives, the qualitative approach of interpretative phenomenological analysis was adopted. Thirty participants were recruited using snowball and purposive sampling (the criteria being that participants had played games featuring customisable avatars) and accounts of their experiences were gathered through semi-structured interviews. Through this research, strategies of avatar customisation were explored in order to demonstrate how people use such systems. The shortcomings in game mechanics and user interfaces were highlighted so that future games can improve the avatar customisation experience.

Elle introduit la notion d'identité-hybride, et propose un cadre analytique pour déconstruire la jouabilité à travers les genres afin de distinguer des moments d’émergence d’identité. Alors que la recherche sur l’identité se concentre couramment sur le joueur ou le personnage-joueur (ou les deux), la notion d'identité-hybride est une forme d’identité fluide, parfois éphémère, qui existe entre le joueur et le personnage-joueur. L’identité-hybride se développe au cours du processus de jeu et inclut nécessairement le joueur (expérience, contexte de jeu, etc. ), l’environnement du jeu (le design, les mécaniques, etc.), et la médiation technologique (ordinateur, console, etc.) qui facilite la jouabilité. Afin de cerner les différents aspects du gameplay qui contribuent a l'émergence de différents types d'identité, un cadre multiforme a été conçu pour isoler les interactions spécifiques? qui comprennent les interactions joueur/personnage-joueur, personnage-joueur/personnage non-joueur, joueur/environnement du jeu, personnage-joueur /environnement de jeux, et joueur/joueur. Il a été associé à un cadre secondaire qui comprend l'examen des spécificités du joueur individuel et la médiation technologique qui facilitent le jouabilité. Une analyse systématique d’expériences de jeu et des éléments de design de trois jeux différents; Mirror’s Edge (DICE, 2008), Alone in the Dark (Eden Games, 2008), et Fable 2 (Lionhead Studios, 2008), a été réalisée pour illustrer les différents degrés d’apparition d'identité dans différentes structures de jeu. En comparant les trois analyses, l'utilité de ce cadre pour mettre de l’avant les éléments qui contribuent au (ou peuvent entraver) le développement de l'identité et, plus spécifiquement, l'apparition de l'identité-hybride, est démontrée. Ces trois exemples jettent les bases d'une discussion plus profonde sur la définition, le contexte, et le processus d’identité-hybride dans les jeux vidéo en général. / Abstract This dissertation examines the complex nature of identity in single-player videogames. It introduces the concept of hybrid-identity and proposes an analytical framework to deconstruct gameplay across genres to distinguish moments of identity emergence. While identity research commonly focuses on the player or the player-character (or both), the concept of hybrid-identity is a fluid, at times fleeting form of identity that exists between the player and the player-character. Hybrid-identity develops during the networked process of videogame play and necessarily includes the player (experience, play-context, etc.), the game environment (design, mechanics, etc.), and the mediating technology (computer, console, etc.) that facilitates gameplay. In order to delineate the different aspects of gameplay that contribute to the emergence of different types of identity, a multifaceted framework was devised to isolate specific interactions between the player/player-character, player-character/non-playing character, player/game environment, player-character/game environment, and player/player. This framework was coupled with a secondary frame which includes examining the specificities of the individual player and the mediating technologies that facilitate gameplay. A systematic analysis of gameplay and design elements of three different games; Mirror’s Edge (DICE, 2008), Alone in the Dark (Eden Games, 2008), and Fable 2 (Lionhead Studios, 2008) was performed to illustrate the varying degrees of identity emergence in different game structures. The utility of the framework is demonstrated by comparing the three gameplay analyses and highlighting the elements that contribute to (and possibly hinder) identity development and more specifically, the emergence of hybrid-identity. These three examples form the foundation for a more in-depth discussion on the definition, context, and process of hybrid-identity in videogame play.
